Purge Control Solenoid Valve
- Disconnect Red-striped vacuum hose from purge control solenoid valve and detach harness connector. Connect vacuum pump to nipple where Red-striped vacuum hose was present. Apply vacuum and battery voltage to valve. With battery voltage applied, vacuum should release. With battery voltage disconnected, vacuum should hold.
- Using an ohmmeter, measure resistance between solenoid valve terminals. At 68°F (20°C), resistance should be 36-44 ohms.
