Power Steering Pressure Switch: Testing and Inspection

POWER STEERING PRESSURE SWITCH INSPECTION

Inspection of Continuity

NOTE:
- Perform the following test only when detected.

1. Inspect as follows if power steering is inoperative.
- POWER STEERING FLUID INSPECTION
2. Disconnect the PSP switch connector.
3. Start the engine.
4. Inspect for continuity between PSP switch terminal and a ground by using an ohmmeter.




Specification

5. If not as specified, replace the PSP switch. If PSP switch is okay but PID value is out of specification, inspect as follows:

Open circuit
- Power circuit (PSP switch connector terminal and PCM connector terminal 1G through common connector.)
- Ground circuit (PSP switch ground circuit.)

Short circuit
- PSP switch connector terminal and PCM connector terminal 1G through common connector to ground.

6. Reconnect the PSP switch connector.
