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
Engine operating condition
Applied vacuum
Result
Idling
50 kPa
(7.3 psi)
Vacuum is held
3,000 rpm

When Engine Is Warm
Engine operating condition
Applied vacuum
Result
Idling
50 kPa
(7.3 psi)
Vacuum is held
Within 3 minutes after engine start at 3,000 rpm
Try to apply vacuum
Vacuum is released
After 3 minutes have passed after engine start at 3,000 rpm
50 kPa
(7.3 psi)
Vacuum will be held momentarily, after which, it will be released

[PCSV 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.
Battery voltage
Normal condition
When applied
Vacuum is released
When discontinued
Vacuum is maintained

5.
Measure the resistance between the terminals of the solenoid valve.

PCSV coil resistance(Ω): 16.0Ω at 20∞C (68∞F)
