Purge Control Solenoid Valve (PCSV) 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.
