OK, so every few engine starts I get a P0446 code.
The car is a 2003 Highlander 2.4L (FWD)
I have tried the following:
1. Replace the GAS CAP with Toyota OEM
2. replaced all of the EVAP hoses at the engine compartment and near the charcoal canister
3. Replaced the both of the VSV valves near the air filter.
My next guess was going to the charcoal canister, but that is significantly more expensive than the other parts.
Does anyone know how to CONFIRM what part it is? (other than taking it to a dealer or shop with more elaborate test equipment)?
