Purge Valve Leak Test

The Purge Valve Leak Test runs only if there was a cold start this ignition, and the Weak Vacuum Test - Stage 1 test did not fail. This test monitors the purge valve for leaks. During the test both the vent and the purge valves close. If a vacuum develops, the purge valve is leaking and a Diagnostic Trouble Code (DTC) P1441 is reported.
