- Tag and disconnect the vacuum lines and harness connector from the valve.
- Connect a hand vacuum pump to the nipple where the green striped hose was connected and draw vacuum.
Connect a 12 volt source to the solenoid and check as follows:
- With voltage applied, vacuum should hold.
- With voltage disconnected, vacuum should bleed off.
- Measure the resistance between the terminals of the solenoid valve.
- Resistance should be 33-44 ohms at 68°deg;F (20°deg;C).
