Hmm. Went to a dealer today to get the Evap Emission Vent valve/solenoid (he gave me a Delco/GM part #25932570, pic attached). I asked him if that was located on the engine. He said no, it's down at the gas tank/Evap Emiss Canister, the one on the engine is the purge valve.
I jacked the car up and I can't see anything that looks like this new part on or around the Evap canister. I looked up the canister on the internet & found photos of all sides of the canister and that new part is not on the canister, unless it's under a cover or located on the gas tank where I can't see it.
I took the top cover off the engine and did locate the solenoid valve (item #3) as you indicated in your thumbnail above. The new valve I got does not look anything like the one on the engine.
You said P0455 was vacuum in the fuel tank when it wasn't supposed to be there. Am I correct in assuming that the purge valve is what opens to provide the vacuum in the fuel tank when needed (during Evap System testing I guess)?
