Solenoid Valve

Disconnect solenoid valve connector. Using an ohmmeter, measure resistance between solenoid valve connector terminals. See Fig 1. Resistance should be 6-11 ohms. If resistance is not as specified, replace solenoid valve.
Remove solenoid valve from steering gear housing. Using jumper wires, connect battery voltage and ground to solenoid valve connector terminals. See Fig 1. Ensure solenoid valve needle withdraws approximately .080" (2.0 mm). If needle valve does not function as described, replace solenoid valve.
