Power Steering Pressure Control Valve: Testing and Inspection

PROGRESSIVE POWER STEERING (PPS) SOLENOID VALVE INSPECTION

1. DISCONNECT PPS SOLENOID CONNECTOR





2. MEASURE RESISTANCE
Measure the resistance between SOL 0 + and SOL 0 -.

Resistance:
6 - 11 Ohms





3. CHECK PPS SOLENOID OPERATION
(a) Connect the battery positive terminal to the solenoid terminal SOL 0 +.

(b) Connect the battery negative terminal to the solenoid terminal SOL 0 -.

(c) Check that the solenoid makes a "clicks" sound. If it is faulty, replace the pressure control valve with the solenoid valve.

NOTICE:
- Do not apply voltage for more then 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
