Celica Forums General Discussion Exterior ECU code. Please Help!

So my CEL came on agian, I took my car to autozone for a free diagnostic and come up with this:

Code: P0441
The PCM has determined that the purge flow in the evaporative emission control system is incorrect for the current engine operating conditions.

and

Code: P0446
The PCM has determined that a malfunction exists in the electrical circuit for the vent control in the evaporative emission contral system.

Can anyone help me interprut what this means and help me figure out how to fix it?? And please don't tell me to reset the ECU. I would rather actually fix the problem. Plus reprogramming my XM and radio is a pain. Thanks for your help guys!

That sure sounds like its related to your gas tank. Double click your gas cap?

It describes what to check.

It also says that a fix can be found on page DI-87
Here is the link to Page DI-87

And what does "reprogramming my XM and radio" have to do with resetting your ECU

^^good shit isaac

I appreciate the info but know what should I do to get it fixed? Should I take it to Toyota or what??

Barrett, Here is the link to Page DI-87

take it to toyota if its under warranty

I have the same problem, However i dont have a dealership near by. When you get things fixed let me know what they did, it would be very helpful so as to not get ripped to bits by some local mexhanic.

Any update on this situation?
