P1446 Fault Code: Understanding The Evaporative Emission System Leak Detection Pump

The P1446 fault code refers to a problem with the EVAP canister vent control valve in your automobile. This valve is located on the EVAP canister and is responsible for sealing the canister vent. It responds to signals from the Engine Control Module (ECM) and when activated, it seals the vent by moving a plunger.

This sealing ability is important for diagnosing other components of the evaporative emission control system.

Normally, this valve remains open, but when it is closed during purge conditions, it allows for the diagnosis of small leaks in the EVAP control system.

If you encounter the P1446 code, it means there is an issue with the EVAP canister vent control valve in your vehicle.
