INSPECTION
When disconnecting the vacuum hose, make an identification mark on it so that it can be reconnected to its
original position.
1. Disconnect the vacuum hose from the solenoid valve.
2. Detach the harness connector.
3. Connect a vacuum pump to the nipple which is connected to intake manifold.
4. Apply vacuum and check when voltage is applied to the PCSV and when the voltage is discontinued.
5. Measure the resistance between the terminals of the solenoid valve.
PCSV coil resistance(Ω) :
14.0 ~ 18.0Ω at 20°C (68°F)
INSPECTION
FUNCTION AND OPERATION PRICIPLE
Purge Control Solenoid Valve (PCSV) is installed on the surge tank and controls the passage between the canister
and the intake manifold. It is a solenoid valve and is open when the PCM grounds the valve control line. When the
passage is open (PCSV ON), fuel vapors stored in the canister is transferred to the intake manifold.
