Description

The purge control solenoid valve (PCSV) is installed on the intake manifold and controls the evaporative purge between the canister and the intake manifold. It is a normally closed solenoid valve that opens when the ECM grounds the valve control line. When the passage is open (PCSV on), fuel vapor stored in the canister is delivered to the intake manifold.
