Evaporative Emission (EVAP) Purge Solenoid

The EVAP purge solenoid is located in the engine compartment attached to the air box. The EVAP purge solenoid controls the flow of fuel vapors from the EVAP canister to the intake manifold in conjunction with its ported vacuum supply. The PCM controls the EVAP purge solenoid by grounding the solenoid circuit. The EVAP purge solenoid is commanded On (PWM) when the EVAP system is in purge mode. Fuel vapors can be purged anytime the PCM is in closed loop and the vehicle is not decelerating.
