Purge Control Solenoid

Purge Valve Vacuum Control Test:

To test the Purge Control Solenoid Valve, located on the engine compartment firewall, proceed as follows.
1. Mark and disconnect the vacuum hose (black with red stripe) from the solenoid valve.
2. Disconnect the electrical harness connector.
3. Connect a manual vacuum pump to the nipple the red striped hose was removed from.

Purge Solenoid Voltage Test:

4. Attempt to apply a vacuum while voltage is applied to the solenoid valve, verify that the valve does not hold vacuum.
5. Remove power from the solenoid valve and verify that the solenoid valve holds vacuum.

Purge Solenoid Resistance Test:

6. Measure the resistance between the two terminals of the solenoid valve, and verify that the resistance is between 36 and 44 ohms at 20 degrees C (68 degrees F).
