Mazda 6 Service Manual: Power steering pressure (psp) switchinspection

Note

• Perform the following inspection only when directed.

Continuity Inspection

1. Inspect the following if the power steering is inoperative (See POWER STEERING FLUID INSPECTION.):

• 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.)

2. Inspect the following harness for open or short. (Continuity check)

Open circuit
