Dodge Journey P0406:  EGR Sensor “A” → Circuit High

P0406 is a generic OBDII Diagnostic code.  It deals with the signal coming from the EGR system.  In this case, it means that the signal coming from the EGR system is higher than the specified range  Since it is a generic code, it has the same meaning for the Dodge Journey as it would any other vehicle.  

The EGR system allows a certain amount of the Journey’s exhaust to re-enter the combustion chamber, which helps lower the emissions coming from your Journey’s exhaust.  When the EGR system has an issue, usually the only thing you’ll notice is the check engine light.  

P0406:  EGR Sensor “A” → Circuit High

P0406 Symptoms:  Dodge Journey

Since the EGR valve is part of the emissions system, there aren’t always symptoms associated with P0406 (other than the service engine soon light).  

Here are the most common symptoms of P0406 when they are present:

• Stalling and/or surging of the engine
• Check engine light
• Higher combustion temp
• Increased emissions output

P0406 Causes:  Dodge Journey

Almost all of the time, P0406 is going to be caused by wiring issues or a bad EGR Valve.  We’ll go over both of them in better detail directly below.

Bad EGR Valve

If you happen to have a good scan tool, you can actually use it to command the EGR valve to open.  If the EGR valve refuses to open it would be time to check the wiring harness for voltage at the plug that goes into the EGR.  If the voltage is OK, then replacing the EGR valve may be a good idea.  There’s plenty on testing this wiring in the next section.

Carbon , junk, and even ice can cause the EGR circuit to stick.  The most common cause of P0406 is the EGR valve.  But, blindly replacing it without testing it can be a waste of money.

If it does end up being the EGR valve, they are pretty affordable .  

Wiring Issues

A great place to start diagnosing P0406 in your Journey is going to be the wiring harness.  Being that the wiring harness that goes to the EGR valve is by the hot engine it has a higher propensity to fail than other wiring in the vehicle, it is often the problem.

Find the wiring harness where it starts at the EGR valve.  Does the plugin have any visible signs of damage?  If it doesn’t, go ahead and inspect the wiring harness for any damage.  You’ll be looking for frayed wiring.  Look close at any place that it may come into contact with the engine, frame, or anywhere that it takes a sharp turn.

To check the voltage at the harness, you’ll need a volt meter.  Check the voltage at the reference circuit.  If it’s at 5 volts, but the EGR Valve won’t open, that’s a pretty good indication that the EGR is bad. 

If you get 12 volts or 0 volts, that would be an indication of a wiring problem.  Here’s a great writeup on diagnosing your wiring issues from AA1Car.com

Most of the time, when P0406 is thrown, it’ll be the EGR valve that is the cause.  It is still a good idea to test it and the wiring before buying a new one though.

POSTED IN pcodes

Welcome to our article on the P0406 code , which indicates a problem with the exhaust gas recirculation (EGR) sensor circuit. If you’ve encountered this code on your vehicle’s diagnostic scan tool, it’s important to understand its meaning and potential causes. In this section, we’ll provide an overview of the P0406 code and its implications.

When your vehicle’s powertrain control module (PCM) detects extremely high voltage signals from the EGR sensor, it triggers the P0406 code . The EGR position sensor is responsible for detecting the position of the EGR valve, and the PCM uses this information to monitor and adjust EGR valve operation. If the signal sent back by the EGR position sensor exceeds the specified range, the check engine light will illuminate, and the P0406 code will be set.

It’s important to address the P0406 code promptly, as it can lead to various issues such as engine pinging , poor fuel economy , and even engine stalling . In the following sections, we will delve deeper into the meaning of the P0406 code, its possible causes, common symptoms, diagnostic process, and potential resolutions.

Key Takeaways:

• The P0406 code indicates a high voltage signal from the EGR position sensor to the PCM.
• Possible causes include a faulty EGR valve position sensor , a bad EGR valve , circuit issues , or a PCM software update .
• Common symptoms of the P0406 code include an illuminated check engine light , decreased engine performance , and poor fuel economy .
• Diagnosing the P0406 code involves inspecting the EGR valve position sensor, EGR valve, and related circuits.
• If professional assistance is not available, consider uploading your ECU file to our portal for a permanent removal of the P0406 code.

What Does the P0406 Code Mean?

The Diagnostic Trouble Code (DTC) P0406 indicates a specific issue with the Exhaust Gas Recirculation (EGR) system. Specifically, it points to a problem with the Exhaust Gas Recirculation Sensor A Circuit, which is responsible for detecting the position of the EGR valve.

When functioning properly, the EGR valve helps reduce emissions by recirculating a portion of the exhaust gases back into the engine intake manifold. This allows for better combustion and reduces the formation of harmful pollutants.

However, in the case of the P0406 code, the Powertrain Control Module (PCM) detects a high voltage signal from the EGR position sensor. The PCM uses this signal to monitor and adjust the operation of the EGR valve. When the signal sent back by the EGR position sensor exceeds the specified range, it triggers the check engine light and sets the P0406 code.

Note: The P0406 code specifically refers to a high voltage signal from the EGR position sensor. It does not necessarily indicate a problem with the EGR valve itself. Further diagnosis is required to pinpoint the exact cause of the issue.

How Does the EGR System Work?

Before diving into the details of the P0406 code, it’s helpful to understand the basics of the EGR system . The EGR system plays a crucial role in reducing emissions by redirecting a portion of the exhaust gases back into the engine for combustion.

The EGR valve controls the flow of exhaust gases into the intake manifold, affecting the air-fuel mixture and combustion process. The position of the EGR valve is monitored by the EGR position sensor, which sends feedback to the PCM.

The PCM uses this feedback to determine the appropriate EGR valve operation, ensuring optimal engine performance and emission control. If the signal from the EGR position sensor indicates an issue, such as a high voltage signal as in the case of the P0406 code, it alerts the driver through the check engine light.

Importance of Resolving the P0406 Code

Resolving the P0406 code and addressing any underlying issues is important for several reasons:

• Performance: A malfunctioning EGR system can lead to decreased engine performance , including reduced power, poor acceleration, and rough idling.
• Fuel Efficiency: The improper EGR valve operation can negatively impact fuel efficiency, resulting in increased fuel consumption.
• Emissions: The EGR system helps reduce emissions, especially nitrogen oxide (NOx) emissions. When the system is not functioning correctly, it can contribute to higher pollutant levels.
• Legal Compliance: Many regions have strict emissions regulations that vehicles must meet. Fixing the P0406 code ensures compliance, avoiding potential penalties or restrictions.

Given the potential impact on engine performance, fuel efficiency, emissions, and legal compliance, it’s crucial to address the P0406 code promptly and perform the necessary repairs or diagnostics.

What are the Possible Causes of the P0406 Code?

The P0406 code can be triggered by various factors, including:

• A faulty EGR valve position sensor : When the sensor fails to accurately measure the position of the EGR valve, it can send incorrect voltage signals to the PCM, leading to the P0406 code.
• A bad EGR valve : If the EGR valve becomes stuck or fails to open or close properly, it can disrupt the sensor’s readings and cause the PCM to receive high voltage signals, resulting in the P0406 code.
• Circuit issues : Damaged wires or poor connections in the EGR sensor circuit can interfere with the proper transmission of signals, leading to the excessive voltage reading and triggering the P0406 code.
• An issue with the PCM : In some cases, the PCM itself may be the culprit. Outdated or faulty PCM software can cause communication errors with the EGR valve position sensor, resulting in the P0406 code. In such cases, a software update may be necessary to resolve the issue.

In summary, the P0406 code can be caused by a faulty EGR valve position sensor , a bad EGR valve , circuit issues , or a PCM software update being required.

What are the Common Symptoms of the P0406 Code?

If you have encountered the P0406 code on your OBD-II scan tool, it is essential to understand the common symptoms associated with this issue:

• Illuminated check engine light: When the P0406 code is triggered, the check engine light on your dashboard will illuminate. This serves as a warning for a potential problem in the vehicle’s exhaust gas recirculation (EGR) system.
• Failed emission test: The P0406 code can result in high levels of nitrogen oxide (NOx) emissions, which can lead to a failed emission test or inspection.
• Decreased engine performance: A faulty EGR system may cause your engine to experience a decrease in performance. You may notice reduced power, sluggish acceleration, or an overall lack of responsiveness.
• Engine pinging: Engine pinging , also known as detonation, is a knocking or rattling sound that occurs when the air-fuel mixture in the combustion chamber ignites prematurely. This can be caused by the malfunctioning EGR system associated with the P0406 code.
• Poor fuel economy: An inefficient EGR system can lead to reduced fuel efficiency, causing you to make more frequent trips to the gas station and spend more on fuel.
• Engine stalling: In severe cases, the P0406 code can cause your engine to stall or shut down unexpectedly. This poses a safety risk, especially in traffic or at high speeds.

If you have experienced any of these symptoms, it is highly recommended to address the P0406 code promptly to prevent further damage to your vehicle and ensure optimal engine performance.

P0406 Code – What Does It Mean & How To Fix It

This is one of the most frequent  OBD2 trouble codes . Read the full article below to know what it means, how to fix it, and what other codes may show related to it.

OBDII code P0406 is defined as a vehicle having an issue with Exhaust Gas Recirculation Sensor A Circuit High.

A P0406 trouble code means that there is something wrong with the exhaust gas recirculation system (also known as ‘EGR’). This particular system is designed to lower combustion temperatures under certain conditions, thereby reducing NOx emissions.

This system is able to do this by recirculating inert exhaust gasses back into the cylinder to be burned with a mixture of air and fuel. Inert gas burns slower than other types of gas and lowers the temperature needed for combustion. The EGR valve is controlled by a computer and opens so that the exhaust gas can flow into the cylinders.

There are a few primary causes in any vehicle that can create a P0406 trouble code. Most of these issues are related to errors with or involving the EGR. The EGR sensor signal circuit could be shorted to a B+ battery voltage.

This can also be caused by an internal failure on the EGR sensor or solenoid. It is also possible that debris is caught in the valve in a way that is holding it open or closed.

There are some common symptoms that you should pay attention to if you suspect a P0406 trouble code may be present. Any of these may be indicative of the P0406 trouble code.

There could be an increase in combustion temperatures and/NOx emissions. The malfunction indicator lamp (MIL) may also be illuminated. You may feel that the vehicle is surging while you are driving it, and the vehicle may stall intermittently.

There is a set of steps that you should follow in properly diagnosing this issue. First, you should check to see if there are any other codes that could be related to the P0406 trouble code. Make sure that you clear your check engine light with FIXD. Take a look at the freeze frame data for the associated temperature of your vehicle and load at the time the code is being set.

Make sure you conduct a visual inspection of the EGR sensor circuit for disconnected and/or shorted wiring. You may also need to remove any carbon buildup within the EGR valve. This is what may be preventing it from closing or opening properly. If the problem seems to persist, you may need to consider replacing the EGR valve .

Common mistakes

The most common mistake includes prematurely replacing the EGR valve without visually inspecting to make sure the EGR sensor circuit isn’t disconnected.

How serious is this?

Fortunately, this is not a trouble code that will prevent you from operating your vehicle. Though, code P0406 may include a variety of vehicle symptoms that could prevent your vehicle from running normally or make your vehicle more difficult to drive. If you notice these symptoms or this code should persist, you should be able to drive it to your nearest dealership.

What repairs can fix the code?

First, you need to perform a general check. Check the wire harness for obvious damage, like chafing and burns, as these both can cause circuit problems. Check for bent or broken pins, corrosion, or evidence of water entry. Repair as necessary and make sure your connectors are properly seated.

Perform an EGR Position Sensor Check. Most EGR position sensors are the three-pin type: reference voltage (Vref), ground, and signal. In the case of our Toyota EWD, these are VC, E2, and EGLS, respectively.

If the EGR valve is vacuum-actuated, you can bench-test the position sensor with a DMM and vacuum-pump. Disconnect the connector and measure across the entire circuit (VC-E2), and you should measure something like 6 kΩ (6,000 Ω). On the signal wire, measuring between VC and EGLS, you should measure somewhere between 0.1 kΩ and 5.5 kΩ (100 Ω and 5,500 Ω), depending on how much vacuum you apply to the actuator port.

If the EGR is electronically-actuated or you want to check output voltages, back probe the connector with your DMM and measure the voltage with KOEO (key on engine off). VC should measure somewhere between 4.5 V and 5.5 V and E2 should measure 0 V. ELGS should measure somewhere between 0.3 V and 4.2 V, which may vary, depending on the valve’s actual position. You can test the voltage output of vacuum-operated valves by varying how much vacuum you apply with the hand pump.

If you measure 5 V on E2, you most likely also measure 5 V on EGLS, which means you have an open circuit back to the ECM on the E2 ground circuit. Skip to Circuit Check to diagnose and repair.

If you measure 5 V on VC and EGLS, but 0 V on E2, you may have an internal or external short circuit. Disconnect the sensor and check for resistance between VC and EGLS on the sensor itself. If you show less than 100 Ω, then you have a short-circuited sensor. In that event, you need to replace it.

If you show between 100 Ω and 5,500 Ω, you may have a short circuit in the wire harness. You can skip to the circuit check to verify and repair it.

If you measure 0 V on E2 and over 4.5 V on EGLS, then you have a fault in the sensor itself. Replace the sensor.

Make sure to check the circuits. Disconnect the ECM and EGR position sensor and measure the resistance on the three wires. Each wire, VC, EGLS, and E2, should measure 0 Ω end to end. Additionally, there should be no connection between any of the three wires or to ground. You should measure at least 10 kΩ between VC, EGLS, E2, and body ground. Repair as necessary.

In the internal combustion engine, the ideal chemical reaction of combustion is as follows: oxygen (O 2 ) + fuel (HC) = carbon dioxide (CO 2 ) + water (H 2 O). Unfortunately, because engines are used over such a wide range of situations, ideal combustion often difficult to achieve. Outside of the lab, for example, there is a wide range of ambient temperature and humidity conditions, atmospheric pressure changes, as well as differing driver demands and even the state of the engine itself, all of which can lead to less-than-ideal combustion. Modern engines employ a number of strategies to achieve ideal combustion in ever-changing circumstances, using systems like variable valve timing and lift, variable ignition timing, direct fuel injection, and exhaust gas recirculation (EGR), to name a few.

The EGR system is designed to reduce the production of nitrogen oxides (NO x ), which are responsible for the formation of smog and acid rain (Nitric Acid – HNO 3 ), amongst other environmental and health hazards. Under ideal conditions, nitrogen (N 2 ) would normally not react with the oxygen during combustion, but abnormally-high combustion temperatures, typically over 2,400 °F, can enable N 2 reactions and the formation of NO x . The EGR system injects a small amount of spent exhaust gases, routed from the exhaust pipe, back into the intake, reducing the amount of O 2 available for combustion, therefore reducing combustion temperatures and the production of NO x .

The EGR system connects the exhaust to the intake via pipes and a valve. The EGR valve used to be vacuum-modulated, but many vehicles have switched over to electronic control by the engine control module (ECM). Depending on demand, the ECM commands the EGR to open and close, controlling the flow of exhaust gas into the intake. The ECM also uses sensors to monitor system function, such as the EGR Temperature or Flow Sensor and EGR Position sensor. If the ECM detects a problem in the EGR position sensor circuit, it will set a diagnostic trouble code (DTC) and illuminate the malfunction indicator lamp (MIL).

Depending on year, make, and model, DTC P0406 may have number of causes. Here are some of the most common.

• Sensor Fault – Because it is constantly subjected to heat from the exhaust, internal electrical faults are a common occurrence. Replace the sensor, clear the code, keep driving.
• Circuit Problem – Certain repair procedures may require disconnecting the EGR position sensor or interfering with its harness. Poor connections, poor routing, chafing, open and short circuits are par for the course. Repair as needed.
• Dodge / Chrysler / Jeep / RAM / MOPAR – A number of models in this lineup have released TSBs (technical service bulletins) addressing DTC P0405 / P0406. Reprogramming the ECM fixes the problem. Check with your dealership to see if your vehicle is covered by any of these TSBs.

Aside from the MIL, you will most likely not notice any drivability problems associated with this particular EGR DTC. Still, because the ECM is now running in “limp-home mode,” you may notice a slight drop in performance and fuel economy.

Because this DTC describes a circuit problem, you’ll need a vehicle-specific EWD (electrical wiring diagram) and a DMM (digital multimeter) to diagnose it.

• General Check – Check the wire harness for obvious damage, such as from chafing or burns, which may cause circuit problems. Also, check for bent or broken pins, corrosion, or evidence of water entry. Repair as necessary and make sure connectors are properly seated.
• If the EGR valve is vacuum-actuated, you can bench-test the position sensor with a DMM and vacuum-pump. Disconnect the connector and measure across the entire circuit (VC-E2), and you should measure something like 6 kΩ (6,000 Ω). On the signal wire, measuring between VC and EGLS, you should measure somewhere between 0.1 kΩ and 5.5 kΩ (100 Ω and 5,500 Ω), depending on how much vacuum you apply to the actuator port.
• If you measure 5 V on E2, you most likely also measure 5 V on EGLS, which means you have an open circuit back to the ECM on the E2 ground circuit. Skip to Circuit Check to diagnose and repair.
• If you show less than 100 Ω, then you have a short circuited sensor. Replace it.
• If you show between 100 Ω and 5,500 Ω, you may have a short circuit in the wire harness. Skip to Circuit Check to verify and repair.
• If you measure 0 V on E2 and over 4.5 V on EGLS, then you have a fault in the sensor itself. Replace the sensor.
• Circuit Check – Disconnect the ECM and EGR position sensor and measure resistance on the three wires. Each wire, VC, EGLS, and E2, should measure 0 Ω end to end. Additionally, there should be no connection between any of the three wires or to ground. You should measure at least 10 kΩ between VC, EGLS, E2, and body ground. Repair as necessary.

ENGINE PROTECTION, i have 406 and 404 error after and post egr valve sobstitution. I have clean fap, and gas recirculation circuit. Why i have error and protection again? How come control all sensor and circuit from – to the bosh control unit ECU?

Mazda 3 del 2004 1.6 TDI. Dopo aver sostituito la valvola EGR con una valvola aftmarket mi risulta un errore 406 alto provo a resettare l’errore ma una volta cancellato l’errore riappare.

fault code po406 on hyundai Tiburon 2l 1999. How easy is it to repair replace the EGR SENSOR

As far as I know, the EGR position sensor is integrated into the EGR valve. It’s not a serviceable part, so you’ll have to replace the whole valve assembly. The only difficulty here is that, because the EGR valve is constantly subjected to exhaust heat, the fittings may be stuck. Plenty of WD-40 and perhaps the application of heat and patience will go far to removing the EGR valve without any collateral damage. You can use a touch of anti-seize lubricant on the threads of the fitting when you install the new EGR valve.

Customer reviews.

very satisfied so far, speedy service and customer friendly, This is my 3rd one in the past year, the last 2 were purchased from a Florida re-builder and both times they failed within 3 months. there prices were higher and there turn around time between 6 to 9 weeks.

A local shop wanted to charge me $4,500 to install a new TIPM, I removed mine and sent it in to Module Masters. They repaired it and had it back to me in a week and I was able to install it and get back on the road!

After reinstalling my Module Master rebuilt TIPM, everything electrical is working correctly!! Thanks so much for a quality job!

Soon, Olga and her son will need to schedule medical exams in Moscow. Can anyone share current experiences with the Filatov or IOM clinics in Moscow?

There used to be complaints about IOM but that was a long time ago. Recently things seem OK there and you get the results the same day assuming your lady doesn't have to run around Moscow getting additional tests which is very unlikely. The Filatov clinic used to be hardly used due to limited hours, being hard to reach, and I think more expensive. But recently a third clinic. MOM, was taken off the approved list for some reason. It used to be one of the main clinics. So Filatov has become more used. I'd probably use IOM but I'm not up on recent experiences there and no one has posted much about medical experiences lately.

I hope those with recent interviews will share about the clinics they used.

I also hope that there are some postings about recent experiences with these clinics. Olga's stress level about the interview is ramping up, so if I can reduce anxiety about the medical exam, it would be good.

Thank you for the reply.

You're right about MOM, excuse me. The other clinic was AO Meditsina. Yes, there is another clinic for a different city but I forget which one. I'm guessing most people use IOM due to same day results but maybe that is true for Filatov also. Of all the clinics, it seems Filatov is the least reported on clinic. Not much feedback.

I looked at prints from the embassy web site from early last year, and you are correct, AO Meditsina was also a clinic. I wonder why they were dropped? Mmmmmm...foreign intrigue!

I'd like to know also. I can share my wife used AO Meditsina and they had her running all over Moscow getting extra tests and lab work for no clear reason. When she returned the next day for results they had her do more tests. Ultimately they OKed her results but she almost missed her interview because of them. Maybe they had a racket going on to make more money? But I never heard of anyone else having this problem so I don't know. It was a very bad experience for my wife to say the least.

I can imagine the stress level for your wife, and also for you. This is why I thought to ask about the clinics. I'd like to reduce overall stress levels for Olga.

She asked me why a medical exam was required, and joking, I told her they are trying to keep out girls with large feet. Her foot size is a little larger than normal. I thought this was funny, but she was not really amused. Olga has a great sense of humor, and it was then that I realized just how stressed she was about the exam and interview.

There hasn't been anyone complaining about medical exams lately that I'm aware of...so all should go well. But you're wise to not take this too lightly either.

I wish you both an easy medical exam and interview.

hello there,

Filatov's clinic is mainly for those with kids, and in general it has had better reviews.

Meditsina was taken off the list back in October because the Embassy did not renew their certification. Word was that they would reapply some time this year. I'd email the Embassy and inquire; the Embassy isn't always that swift to update their website. They are the best with nice lobby with piano player; like at Bloomingdales!!!

From what I remember from when Alla and Leonid did their medicals last year (Alla got in under the wire at Meditsina) is that Filatov is only doing children (may have changed by now) and IOM was the last resort. Read some of the medical report that can be found around the October - December timeframe last year as there were a few reports from IOM (lots of walking from building to building but not too bad).

hello there, Filatov's clinic is mainly for those with kids, and in general it has had better reviews. If Olga is interested, she can read the Russian-girls-analogue of VJ http://www.zaokeanom...um/forum24.html But overall, she has nothing to worry about, much as I have read on medicals in Russia, NO ONE has been denied a visa due to medical reasons...or no one posted on such experience . Good luck to you and Olga.

Thank you. This information is helpful. Olga's son is enjoying this process. For him, it is a big adventure. He is more excited about meeting my Chow-Chow dog than anything else. Olga is feeling some stress now, because the pace of activity has increased. She will be OK. I will definitely point her towards that forum.

Tell her to be careful about what she reads on these other forums. I know that Alla did a lot of "research" on these types of forums during our visa waiting process and she read a lot of "horrible movie" stories of other Russians' experiences while living in the US. I was always able to counter these stories and she did her own "verification of the facts" but she may be bombarded with negativism. If she wants/needs, I can have Alla get in contact with her (email or Skype or phone) if she wants to talk to someone live and "been through it".
