Disconnect the vacuum hose from the solenoid valve.
Detach the harness connector.
Connect a vacuum pump to the nipple to which the red-striped vacuum hose was connected.
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 |
Measure the resistance between the terminals of the solenoid valve.
PCSV coil resistance (Ω) : 26.0 Ω at 20℃ (68℉)
