Hyundai Elantra MD/UD: Purge Control Solenoid Valve (PCSV). Description and Operation
Description
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 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.
