4. Warm up the engine to normal operating temperature.
5. Turn the ignition switch to ON.

Specification:




6. Measure the voltage at PCM terminal 31.
- If not as specified, check the related harness and power steering pressure switch continuity.

Inspection of Continuity

1. Disconnect the power steering pressure switch connector.




2. Connect an ohmmeter to the power steering pressure switch.




3. Start the engine and let it idle. Check continuity of the power steering pressure switch while turning steering wheel.
