P0401 EGR insufficient flow – Chrysler Minivan

It has been reported that
late model Chrysler Minivans would display P0401 egr inadequate flow codes P0401-P0408. The egr valve works in a similar way to a solenoid in that it pulls the pintel from its seat. Located at the top of the valve, a position sensor monitors the difference between how far the pintel shaft has actually moved and how far the computer instructed it to go. It’s the position sensor that fails in this case (see plunger in photo). The sensor may be the source of the problem, but the solution is to replace the complete egr valve.

You must acquire the gasket that fits between the valve and the intake air tube, as this gasket does not included with the new valve.

Wait until the engine has cooled down before continuing.

Remove the two bolts that hold the intake air tube to the top of the valve in place and set them aside.

  1. Because it looks that the alternator is in the way, removing the bottom bolt can be a bit difficult at times.
  2. Simply swap to 14-in drive sockets and an extension, then fit it over the bolt head to complete the installation.
  3. After that, connect the intake tube to the top of the engine.

Chrysler Town and Country P0401: EGR – Insufficient Flow Diagnosis

P0401is a typical OBDII fault code that will appear in theChrysler Town & Country and other Chrysler vehicles. It has anything to do with the emissions system and is abbreviated as: The EGR system on a vehicle is in charge of recirculating exhaust gases in order to reduce the vehicle’s emissions production and reduce pollution. It is divided into three major components by the Town and Country’s EGR system. The EGR Valve, the Differential Pressure Sensor, and the Actuator Solenoid are the components in question.

P0420 Chrysler Town and Country is related to this.

Chrysler Town and Country P0401 Symptoms

The majority of the time, when P0401 is triggered, there will be no symptoms other than the service engine light turning on quickly. If the situation is acute, you may hear a faint pinging or knocking sound.

  • The service engine soon light will be on when the code P0401 is entered. There may be a distinct knocking sound that emanates from the car under certain circumstances. It’ll sound nearly like a piston smack when it happens.

P0401 Causes: Chrysler Town and Country

In most cases, determining what is producing the P0401 code in a Town and Country is not difficult to determine. The following are the most often seen reasons:

  • Blocked EGR Tube — Over time, the tube that transports exhaust gases back to the engine may get clogged with debris. It can also get twisted or kinked as a result of this. Particularly relevant if you are encountering P0401 shortly after doing engine maintenance. Examine the tube to see if it is fractured, blocked, or otherwise damaged
  • And In most cases, the EGR valve itself will not be the first location to look for issues with a vehicle’s performance. However, they are undoubtedly the root cause of P0401 on a regular basis. Engine Vacuum Issues – The EGR valve is dependent on engine vacuum to function properly. In other words, if you are seeing P0401 and other codes, it is possible that the P0401 is an indication of broader issues. As an example, if the motor is not operating properly in order to provide adequate vacuum to activate the EGR valve, the code P0401 will frequently be generated. Sensor Failure — The Differential Pressure Feedback-EGR sensor might become defective, causing the EGR valve to become inoperable and the code to be generated.

Town and Country P0401 Fix

Blocked EGR Tube — Over time, the tube that returns exhaust gases to the engine may get clogged with carbon deposits. It can also get twisted or kinked as a result of the above circumstances, as well. When encountering P0401 immediately after performing engine maintenance, this is especially true. Observe the tube to check whether it is fractured, clogged, or otherwise compromised. In most cases, the EGR valve itself will not be the first location to look for issues with the vehicle. P0401 is most typically caused by them, however they are not the only ones.

P0401 and other codes may be an indication of a broader problem if you are experiencing them together in your system.

An issue with the Differential Pressure Feedback-EGR sensor might cause the EGR valve to cease functioning correctly, resulting in the code being generated.

  • Make a visual inspection of the EGR tube since it’s a common source of P0401 problems, and it’s simple and quick to perform. It’s also reasonably priced, making it an excellent choice for most people. Unless it’s cracked, you’ll have to get a replacement. If it’s clogged, you can get away with cleaning it and replacing it
  • Otherwise, you’ll have to replace it. Check the DPFE Sensor Voltage- If you are comfortable working with a voltage meter, go ahead and test it yourself. Here’s a nice post on how to do it from It Still Runs that can help you out: How to Perform a DPFE Sensor Test
  • Test the EGR Valve- A vacuum gauge can assist you in determining whether or not the EGR valve itself has failed. It can be tested using an avacuum gauge, according to this article from Autozone.

Conclusion

Make a visual inspection of the EGR tube because it’s a common source of P0401 problems, and it’s simple and quick to perform. It’s also reasonably priced, making it an excellent investment. This means that you’ll have to replace it if the old one is cracked. If it’s clogged, you can get away with cleaning it and replacing it; if it’s not, you should replace it immediately. Make a check on the DPFE Sensor Voltage, if you are confident in your ability to do so. It Still Runs has a fantastic post on how to go about doing so: Instructions on how to test the DPFE sensor Vacuum gauges can be used to assess whether or not the EGR valve is faulty in the first place.

p0401 egr problem

Posted on September 28th, 2016 at 12:17 PM Date of joining: June 2011 Number of posts: 69 The exhaust gas recirculation system (EGR) is a constant source of humor and annoyance. I’ve had EGR codes on and off for years, and each time I believe it’s fixed, it turns out to be a false alarm. A sensor, which I recently found, is located in the Intake Manifold and measures pressure and temperature. Chrysler does not appear to have mentioned it anywhere. I had nothing to lose, so I took it out (with one bolt).

This sensor has four wires connected to it, and it is located just behind the OIL Dipstick.

Check Engine Code P0401 – How to Diagnose and Fix It

What does the P0401 code represent? What causes this check engine code and how to resolve it will be revealed by a mechanic who has dealt with it a countless number of times. It signifies that there is not enough exhaust gasses flowing back into the incoming air to the engine, as indicated by the fault code ‘insufficient EGR flow.’ EGR is an abbreviation for ‘exhaust gas recirculation.’ A three-part system, the EGR system is composed of the EGR valve, the DPFE (differential pressure sensor EGR), and the actuator solenoid.

This contributes to the reduction of emissions.

EGR systems were formerly regulated by the engine vacuum through the use of pipes and valves. The majority of them are now operated by solenoids, which are electrical devices.

What Causes the P0401 Code?

  • Incorrectly functioning EGR Valve or EGR Passageway
  • Incorrectly functioning EGR Control (no or low vacuum)
  • Incorrectly functioning solenoid or wiring

Less Common Causes

  • Incorrectly functioning EGR Valve or EGR Passageway
  • Incorrectly functioning EGR Control (no or low vacuum)
  • Faulty solenoid or wiring

How to Fix Engine Code P0401

However, while every automobile manufacturer has their unique EGR system design in place, the most common two reasons of this code are either a faulty valve or clogged passageways in the intake manifold (many times the intake manifold has extremely narrow passages that become clogged with soot). Many times, this code is caused by clogged EGR channels, and removing the sensor may allow you to get access to the clogged EGR passageways in order to clear the code. Another thing you may do on your own is to double-check all of the vacuum hoses and all of the cabling that leads to the EGR valve.

A DIY technician will have a more difficult time diagnosing this problem code unless they have a lot of knowledge and access to specialist instruments.

If you don’t have the necessary knowledge or time to analyze the problem, you might want to try just replacing the EGR valve as a first step.
