Reading the OBD code is easy, finding the actual problem is the hard part
go to
If I have to remove the EGR valve, I'd rather just replace it. Are they expensive? Are there after market parts?
auto zone, cost me about $35.00 for one. discount auto parts(advance) want $59.00 dealer wanted $65
Well, I went to auto zone and they charged me $59.
According to my Haynes book, the EGR problem can cause engine overheating and detonation. My car seems to run OK too. I have the new EGR valve but the EGR pipe is on so tight I can't turn it loose.
let the car sit and try it when the engine is cold in the morning.. it is probably the heat that is swelling the pipe or fitting and not letting you take the tube off.. on my 96 contour V-6 enginer 2.5 lt. the tube came right off....... it looked a lot tighter than it was.. just one sharp pull on the wrench and it was like hand tight.....
overheating
I, and many another, have had this problem. The DPFE sensor is a common problem on this car. Replaced it on mine and it went away. Luckily I have a datalogger and was able to log the voltage out of the sensor while driving with the old and new one.
You said that you replaced the EGR valve, I'm guessing that didn't work, or at least might have for the time being? I wonder if it's too late to return it if you just need the DPFE sensor.
