2006 Chrysler Sebring convertible Limited 2.7 V6 does NOT have an EGR (confirmed by a Chrysler expert). However, my PCM is throwing EGR error messages and the MIL/CEL is on constantly, preventing me from getting the car smogged.
Mechanic "found codes P0406 & P0403 for EGR position sensor high and EGR solenoid circuit open, vehicle has no EGR valve, recommended replace PCM"
Has this happened to anyone? Did you replace the PCM or find another solution? If you replaced the PCM, is it difficult for a backyard mechanic?

 

PCM is a very simple replacement. Search on the internet for PCM replacement services. You order the PCM giving them your VIN and mileage. They program the PCM for your vehicle and send it to you. It's plug and play. You send the old on back to them for refurbishment. Here's one place: https://carcomputerexchange.com/
There are others.

 

THANK YOU. Will do that.

 

The "new" PCM didn't change the CEL / MIL light, which remains lit.

 

What is the code you are getting now? If you don't have a code reader, try the "key dance". Key on-off-on-off-on. Codes should appear where the trip odometer is.

 

The same two EGR codes, P0404 and P0406. But, again, there is no EGR on this engine.

 

Well those two codes says there is one. So if using your vin the software installed says it is looking for one. Now was this engine swapped over from a different car? if so that's likely the issue.

 

I have no evidence of an engine swap. I sure wondered. The car was smogged when I bought it, and I smogged it last time. The CARFAX shows no indication of a swapped engine. Except for this current problem, nothing indicates a swap (no weird behavior, no physical signs of modification).

I hope California will let me smog it somehow.

 

I have a 2001 2.7L convertible. I have a shop manual for that year and there is an entire section on the EGR system including both the 4 cylinder and the 6 cylinder (2.7L) engines. They have pictures of the components of the EGR system of the 2.7L engine. I also have an electronic shop manual for 2002, and while there is a reference to an EGR system for the 2.7 but it is only one small paragraph and there are no pictures. There is extensive mention of the system for the 4 cylinder engine. It would appear that they figured out a way to eliminate the EGR system for the 2.7L engine in 2002, but it's very strange that a code could be generated relative to that system unless codes are stored in the body computer prior to shoving them out the OBD port. I don't know how that might work. Did you try clearing the codes with the code reader to see if they will come back? In California you can't get codes read at an auto parts store, so if you don't have a code reader you'll have to pay somebody to do that. Code readers can be bought for less money than a dealer would charge to hook theirs up one time, so you might consider that as an option. They are handy to own.

 

OMG Yes, I have searched and searched, and two other mechanics searched, and there is nothing but confusing information. However, the mechanic I most trust, 30 years in a Chrysler dealership shop, knew exactly what I was talking about, popped the hood and pointed to two locations which were sealed off by Chrysler that would have been the EGR ports. He said that some 2.7L V6 engines in 2006 did not have EGRs. He also said I should replace the computer.

But that didn't work. (Although to be fair, he wanted to replace it with a $1,400 new Chrysler PCM, while what I did was order a $200 used computer reprogrammed to my car.)

I assumed that it would be "reset" each time it sat without any electrical power (the battery had to be replaced, it died) and when I swapped the computers. I had gone to AUTO ZONE and they read the codes, giving the same codes I got on my bluetooth reader, but they can't reset it. Maybe all those "interruptions" did not actually reset either PCM? I have the cheap version of the bluetooth reader, maybe if I cough up the $75 for all the bells and whistles, that might clear the codes?
