pulled codes

[pun]

just bought a code reader, pulled codes and this is what i got.

KOEO

84-EGR VENT fault
63- throttle position cicuuit fault, below min voltage.
31- EGR valve control sensor fault.



can anyone tell me what they mean, and how to fix them.

Sounds like your TPS is bad, or maybe the screw on the throttle body is to far out. As for the EGR codes here is what I found on testing them. It doesnt make much sense to me but maybe you will know what to do. Sounds like the EGR valve is going bad, or the vacuum to it isnt up to par.

good now that u have a code reader ur life will get simpler first go out and disconnect the negative battery terminal for a good five minutes. who knows how long those code have been there. disconnecting ur battery will clear the codes. drive for a day or two or when the truck starts to run rough again then u know for sure thaat the codes coming up are the ones that need to be addressed then go from there u can pm me if u wish good luck
