Check Engine Light on Due to EVAP Vapor Canister Fault on Toyota Celica

Problem Description and Possible Solution

The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.

Code P0446. Took it to the dealer and they said:
$450 parts to replace the Vapor Canister.
$600 labor to replace the canaster which involves:
- removing the gas tank
- dropping the suspension to remove the gas tank
- replacing the Vapor Canister
No coverage from Toyota.

I need to get my car inspected.
You do not have to drop the gas tank but you do have to drop the suspension it's only 6 bolts one of which is doing dubble duty also holding the charol canister so their is only 7 bolts total Disconect 3 hoses and 2 electrical plugs. Reconnect to new unit Replacing entire unit cost all new under $ 350. 00 Take the tires off and use jack
