Thread: Evap Nightmares?

Schoen- Located on top of fuel tank.

Sounds like problems could be related. Conditions for setting P1441= The PCM detects vacuum during a non-purge condition. If the purge soleniod is stuck open, your engine vacuum is being diverted always to your fuel tank, possibly messing with what your vacuum controlled sensors are reading.

I am having the same code with my 98 GTP. It doesn't ever have any adverse effects but is annoying. I reset the SES light every few days with my code scanner but it keeps coming back.

Id guess if the purge was sucking fuel from the tank it could run rough but i doubt fuel would make it past the canister. Un plug the purge and see if the problem persists.

If you un plug it (electric part) and you still feel vacum on the fuel tank side then the purge is bad and unplugging it will not help.

Well same thing happened to my brothers VW Jetta his but in his case car would run perfectly until it came to fill up the tank. Every time he would fill up or the car would stay out in a really sunny day the car wouldn't start right away, also like 5 to 10 min to get it to start.

Turns out it was the canister purge valve (N80) in his case, that was stuck open all the time and when it came to fill up the tank the fumes from the tank would flood the engine , or so we where told, took it off and cleaned the valve with carb. cleaner, works great for now while he picks up a new one.
