I have been getting a soft code after the car has been running for a few minutes and goes off when I restart the car.

KOEO tests came up

335-EGR sensor voltage out of range
332-EGR valve opening not detected

KOER tests came up

538-Insufficient change in RPM
326-EGR circuit voltage lower than expected

let me take a stab at this....EGR problem?:rolleyes:
not sure about the insufficient RPM error though. Any ideas.
 
alright, I guess I didnt hit the throttle on the right point of KOER test so thats no big deal, I will do that one tomorrow.
I also read that the EGR being stuck closed is NOT a bad thing??:confused: should I try and fix it..I just dont like the CEL on.
 
Ignore the rpm code. Your cel will be on as long as you egr is not checking out. It can be removed on the computer. Otherwise, your gonna have to fix it to remove the cel. If you want replacement parts for it, you can have mine. I removed my entire system. It could be the transducer or solenoid. I have both. Your welcome to them.
 
that would be great, I will do a block off plate and use the ones you have to clear the CEL code, I will PM you.
