Looks like something in my evap system went wrong again. From what i researched it either is a faulty gas cap or something wrong with the evap system.

When i first got the car i had to take it into the dealership for an issue with the evap system (code p 0440). Im wondering if it could be the same gremlin again.

If anyone has dealt with this and fixed it please lmk what you did.

Thanks in advanced.

I get this code sometimes on my 2000 ES< mostly when the tank is 1/4 full or less. There was a how to somewhere on here about how to fix it. You need a hose that goes from the ldp to the tank to fix it iirc. the hose is obsolete and you can get a pt cruiser pvc hose as a replacement, again if I can recall correctly. Maybe someone else will chime in with better info. I think it was occasional demons who posted the info. Best of luck with this. Try searching the how to's. he had good info with pics and the part # for the hose.
