Power Steering Pressure Switch: Testing and Inspection

NOTE: Perform the following test only when directed.

1. Inspect the following if the power steering is inoperative
- Power steering fluid level
- Power steering fluid leakage
- Power steering fluid pressure

2. Disconnect the PSP switch connector.
3. Start the engine.

Specification:

4. Inspect for continuity between the PSP switch terminal and GND using an ohmmeter.
- If not as specified, replace the PSP switch.
- If the PSP switch is okay, but PID value or PCM terminal 31 voltage are out of specification, perform the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection
1. Disconnect the PCM connector.




2. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
3. Tighten the connector attaching bolt.

Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}

4. Inspect the following harness for open (Continuity check).

Open circuit
- If there is no continuity, the circuit is open. Repair or replace the harness.
- PSP switch terminal and PCM terminal 31
