Help with EVAP Vent control valve SES Code P0455
#31
Guys,
So I tried and bought the Dorman part 911503, no luck. I still have the SES light on for the same code.
I also went and got a OEM new gas cap and no luck. Still the same issue.
What is next?
Would I have to buy the Vapor Canister Purge Valve, Rock Auto has price of $105.79. (STANDARD MOTOR PRODUCTS CP743 Intermotor Solenoid)

UPDATE: Fixed
Guess it was the EVAP Canister Purge valve. After a day or so I checked the car for codes, pending codes and monitor readiness and found everything was all set. I erased the computer again (to double check) and put the original gas cap back on (because aftermarket doesn't have the loop that holds the cap to the car) and after 15 miles or so, the monitors all reset and everything is good.
So for me, my P0455 WAS the EVAP purge canister valve. $40ish from Rockauto for the Dorman part.
I checked the old valve again. I applied 12V to it and while the solenoid clicked, i checked for airflow through the valve by blowing on it (i didn't do this before) and found that the valve was not closing properly like it should. So the original valve did fail even though the solenoid was working.

G35 sedan w/ too much money in mods
Nissan/Infiniti issued a warranty extension last year on the Evap system for first gen G's, stretched it to 15 years/150K miles mainly due to problems with filling the gas tanks on a lot of models. It applies even if you're not the original owner and they are still honoring that. Our 05 sedan is 14 years old at this point and 147K miles on the odometer and we took it in a little over a month ago to have the work done. I was the second owner, bought it in 09, and they managed to find me to mail me the letter explaining the change. They had it done in a day and didn't cost us a penny so check your local Infiniti dealer before you spend any money fixing your issue.

Not really. In my case it was the valve at the rear of the car...so I never got that far.

then you say it was the canister vent solenoid that fixed the problem by posting the part number for it when someone asked which part they needed to buy.
And finally when someone asks again, you say the part you needed to change was located in the rear of the car, which is contrary to the fact you stated the canister purge was the fix, in which that part is under the hood as you described.
pretty useless thread imo. Nobody seemed to give a definitive answer for a solution but this one by mustang was very misleading, though likely unintended. I really wonder what part he actually replaced lmaoooo
