What does the p0440 code stand for?
If the cap will not seal or hold vacuum/pressure, then it can trigger the P0440 code. Verify that the Purge Valve and the Vent Valve work properly and hold vacuum for a sustained amount of time—at least thirty to sixty seconds. If either one of these valves function improperly, the system will not develop and/or hold the proper amount of vacuum.
How does the p0446 Chevrolet evaporative emission vent system work?
P0446 Chevrolet Meaning. The Powertrain Control Module (PCM) monitors the performance of the Evaporative Emission (EVAP) system by applying a predetermined level of vacuum to the EVAP system then monitors the vacuum decay rate.
