Evaporative Emission Control System

Inspection

[System Inspection]

1. Disconnect the vacuum hose from the throttle body, and connect a vacuum pump to the vacuum hose.
2. Check the following points when the engine is cold [engine coolant temperature 60°C(140°F) or below] and when it is warm [engine coolant temperature 80°C(176°F) or higher].
When Engine Is Cold





When Engine Is Warm






[PCSV Inspection]

NOTE:
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(Ohms):16.0Ohms at 20°C (68°F)
