  • Power steering fluid level
  • Power steering fluid leakage
  • Power steering fluid pressure

2. Disconnect the PSP switch connector.

3. Start the engine.

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 PSP PID value is out of specification, perform the Circuit Open Inspection.
Specification

Circuit Open Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION.)
