Celica Forums General Discussion General Check Engine problems

I have a 2000 gts and my check engine light came on. After i did a scan these codes came up: P0440 Evaporative Emission Control System Malfunction, P0441 Evaporative Emission Control System Incorrect Purge Flow, P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. Can anyone tell me what any of these mean and what i have to do to fix them??

thanks

do you have any aftermarket parts such as CAI or exhaust? it would almost sound like something with the cat to me?? take it to a dealership man

My car is stock (no aftermarket parts). I have taken it to the dealership and they charged me $35 to say my gas cap was loose. Its funny cause a few days later the light came back on and i had not touch the cap.

Take it back to them and get your money back or tell them to fix the gas cap if it's so broken.
