Check engine and VSC lights come on, even after re-setting ECM. Get trouble codes P0441, P0446, P0455, P2418. Fuel Cap fits on good. Checked filler fuel lines, removed cover to expose vapor canister: no visual crack or tears in hoses. What are the other possibilities?

Hello,

I would check up at the engine to check the VSV which is the valve that controls the EVAP system. Check for broken hoses and test across the terminals to make sure the valve is not shorted.

Here is a guide on how to use a volt meter:

Please let us know what you find.

Cheers, Ken
