Component Tests and General Diagnostics

Purge Control Solenoid Valve Location:

1. Mark and then disconnect the vacuum hoses (non-striped, red striped) from the solenoid valve.
2. Disconnect the harness connector from the solenoid valve.
3. Connect a hand vacuum pump to the nipple on the solenoid valve (the point at which the red striped hose was connected).

Purge Control Solenoid Valve Inspection (Operation) For Turbo:

4. Apply vacuum to the solenoid valve and verify that when power is applied vacuum leaks and when power is removed vacuum holds.

Purge Control Solenoid Valve Inspection (Coil Resistance):

5. Using an ohm meter measure the solenoid coil resistance. The resistance should be 36 - 44 ohms @ 20 °C (68 °F).
