Re: Check Engine Code P0446
The error code P0446 means "EVAP System - vent control malfunction". This error code can be caused by any of the following :
Open or short in VSV circuit for EVAP
VSV for EVAP
Open or short in vapor pressure sensor circuit
Vapor pressure sensor malfunction
Open or short in VSV circuit for vapor pressure sensor
Malfunction in VSV for vapor pressure circuit
Vacuum hose blocked, damaged or disconnected
Charcoal canister malfunction...
I do think that this is something that you should look into having repaired as soon as possible to prevent further engine problems. Also, this might possibly hender your gas mileage and engine performance.
