Engine Code Help
 

I'm getting a code 034 EVP/PFE High. I get this code with the KOEO and KOER. The EGR valve and EVP Sensor is new and so is the IAC. Can anyone help with why I'm getting this code and what to do?

When I pulled my codes a while back, I got a code 31 that said my EVP/PFE circuit was below minimum voltage. I know yours is saying it is high, but you may try this anyway. This is the reply I got from PKRWUD, who used to be a regular contributor on these boards:

Code 31 means there's a problem with your EGR valve, or more specifically, the sensor that measures it. Disconnect the harness at the EVP sensor, and jump the brown/green wire and the orange/white wire. Run KOEO self test again, and look for a code 35. Ignore all other codes. If a code 35 comes up, replace the EVP sensor.

I know you said you have a new EVP sensor, but you still may want to jump those wires to make check and make sure the new one is not bad. When I did mine, code 35 came up. I replaced my sensor and haven't had problems since. Hope this is of some help.

Thanks for the help. I have spoken with PKRWUD before too. I will give it a try.

Cool. Let me know what you find out.
