Purge Control Solenoid Valve (PCSV)

Description and Operation

Description

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

Installation

Install the component to the specified torque. Be careful not to drop the component, as internal damage may occur. If dropped, inspect it before installation. Do not apply oil or grease to the hose ends when connecting the PCSV hose. Do not allow foreign material to enter the valve.

1. Install in the reverse order of removal.
