The check engine light has been coming on so I went to AutoZone where they read P0406 which is "The voltage signal EGR sensor "A" is too high for the current engine operating conditions". The van runs fine so should I worry about this? If so, can an average mechanial guy like nme fix it? I'm thinking I should replace the sensor first before checking the EGR valve.

Any help appreciated. BTW 2005 Caravan 3.3L V-6.

 

No warranty? 3/36?

 

56K miles right now. Out of the 3/36.

 

Its not a sensor.
start the car.
Check for 12volts and a ground at the egr solenoid connector.
if you have both, replace the egr valve. You should take your car to a dealer from now on.
Does anyone know of a forum similar to this one but for Chrysler-Dodge-Jeep Dealer techs only?

 

I have a 2005 dodge ram quad cab with 40k. I had the same problem with p0406 code. Dealer said this wasn't warranty. wanted about 450 to 500 to clean out egr valve. Flush out the carb in the system I was told. did some research and found out that you can take it out and clean it. but I decided to just buy a new one, about 60 at dealership. I am not a mechanic so it took me a while to find it. On my truck it was on top, back of the motor by intake. and once I bought the new one, I knew what to look for. Had to take the air box off to reach it better. It was hard to get to but I managed to replace it. afterwards, I took off neg cable to battery for a few seconds to reset code. so far three weeks and no light! Hopes this helps someone that has the same problem. these forums helped me out alot.

 

Bad advice. Very bad.[]
