Canister Purge Diagram:






DESCRIPTION
The Canister Purge (CANP) valve is part solenoid, part valve output component that is used by the Powertrain Control Module (PCM) to regulate the flow of fuel vapors from the evaporative canister to the fuel system. The CANP valve regulates the flow as a function of manifold vacuum and duty cycle signal from the PCM, which controls the CANP valve solenoid.
