How To Test and Replace EVAP Canister Vent Control Valve P0446

The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid responds to signals from the ECM. When the ECM sends an on signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is a necessary part of the diagnosis algorithms for other evaporative loss system components.

EVAP Vent Solenoid Code - P0446
Let's have a look at this Chevrolet Cobalt that came with a code P0446 for the EVAP Vent Solenoid Performance. I have notice that most people will get sucked into the trap of changing parts based on code definition instead of code setting criteria. Let's have a look at this car and see how the code could send you down the wrong path if you don't look at the EVAP system as a whole to make a fast diagnosis.
