No Stat After Refueling - Need EVAP System Clarification
The car in question is an 05 CTS 3.6L V6, the complaint is that the vehicle refuses to start after refueling. Car has P0456 / P0451 trouble codes if my memory serves me correctly.
When looking for online instructions and parts I saw that there are both a evap control solenoid and a canister vent valve. I suspect the canister vent valve to be attached to the canister itself, which I believe to be located right atop the rear differential. The purge solenoid I believe to be located on the passenger side rear of the engine. Can anyone confirm that I am indeed correct?
However, I was unable to find anything to do with the canister vent valve. Anyone have additional information? I suspect it's held in there by a single bolt and an o-ring, but I just want to make sure.
Also, if anyone knows specifically which part is at fault, I would rather not replace both unnecessarily unless I have to. I suspect CP480 more than the 15788844 (canister vent valve).
Any and all information is appreciated, thanks.
Just to clarify, are these two the correct parts? (Part #15788844 and CP480)
