Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Solenoid Valve Test
Disconnect solenoid connector. Using an ohmmeter, measure the resistance of the solenoid valve. See Fig 1 . Resistance should be 3.4-6.9 ohms. Apply 12 volts to one connector lead and ground the other. Solenoid should operate with a noticeable sound. Replace solenoid if there is no continuity or solenoid does not operate.
