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.
