Canister Purge Solenoid: Description and Operation
Cannister Purge Valve.
PCM Wiring.
PURPOSE
The canister purge solenoid is used by the PCM to control fuel vapor flow from the carbon canister to the intake manifold where it is burned in the
combustion process during engine operation. This helps reduce the amount of hydrocarbons (HC) emissions emitted into the atmosphere. The
PCM will supply a ground to the solenoid opening it and allowing fuel vapors to flow from the canister to the intake manifold. When the ground is
removed the solenoid will close.
LOCATION
The Cannister purge solenoid is located on the intake manifold.
