Description And Operation: Description

Installed on the intake manifold, the Purge Control Solenoid Valve (PCSV) controls the evaporative purge between the canister and the intake manifold. It is a solenoid valve and is open when the ECM grounds the valve control line. When the passage is open (PCSV ON), fuel vapor stored in the canister is transferred to the intake manifold.
