Canister Purge Solenoid: Description and Operation
EVAP Purge Solenoid Operation
EVAP Purge Solenoid Location
LOCATION
The Duty cycle purge solenoid is mounted near the Anti-lock Brake System (ABS) Controller.
PURPOSE
Powertrain Control Module (PCM) controls timing and rate of purge flow, by varying solenoid pulse width, (the length of time solenoid is
energized per cycle).
OPERATION
PCM controls solenoid by applying and removing solenoid ground.
During open loop operation, (including cold start up and hot start time delay), the PCM DE-ENERGIZES the solenoid, preventing canister purge.
When the engine enters closed loop, (after warm-up and time delay), PCM ENERGIZES and DE-ENERGIZES solenoid approximately 5 to 10
times per second, depending on operating conditions.
NOTE: Solenoid will not operate unless installed correctly. The word TOP should face up when installed.
