My Engine light came on last night on our way home, so we went by Autozone to have them scan it and the code came up a P446. Looking at past threads here, I hoped that someone would be able to tell me exactly what the code is and how I can help out my car.


Thanks in advance

P0446 Evaporative Emission Control System Vent Control Circuit Malfunction

Basically, you didn't tighten up your gas fill cap. Make sure you tighten the cap on every fill, and it won't come back. IF it does, it idicates a problem with your evap-emissions system and should be looked at by a dealer. There should be a 7year 70,000 mile warranty on any emissions related parts, so even if your normal warranty has expired, your emissions warranty may still cover it.
