Power Steering Valve: Testing and Inspection

1. Disconnect the Progressive Power Steering (PPS) solenoid connector.





2. Measure resistance. Measure the resistance between SOL (+) and SOL (-).
Resistance: 6.0 - 11.0 ohms.
3. Check the PPS solenoid operation, as follows:





a. Connect the battery positive terminal to the solenoid terminal SOL (+).
b. Connect the battery negative terminal to the solenoid terminal SOL (-).
c. Check that the solenoid makes a click sound. If faulty, replace the control valve housing with the solenoid valve.

NOTICE:
^ Do not apply voltage for more than 30 seconds to avoid burning out the solenoid.
^ If repeating this step, wait until the solenoid cools down enough that it can be touched by hand.

4. Connect PPS solenoid connector.
