Pontiac P0446 Evaporative Emission Vent System Performance Diagnostic Trouble Code, Definition, causes, And diagnosis Guide


What does this mean?

Interpretation of OBD2 Code P0446 Pontiac:
The exhaust valve has only one purpose. It closes to close the discharge so that the EVAP machine can be compressed and ensures no output. The evap release valve is usually supplied with Batt. key electronics. The ECM operator controls the ground, and when it is stabilized, it operates the valve (closure). When the ECM detects that it is running low, open, or small battery volume on the control panel, the P0446 Pontiac will stabilize. The code may also translate to ECM recognizing that the EVAP system may not be able to complete or clean the test.
