POWER STEERING PRESSURE (PSP) SWITCH INSPECTION [L8, LF, L3]

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 [L8, LF, L3].)

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

Open circuit

• If there is no continuity, the circuit is open. Repair or replace the harness.

- PSP switch terminal and PCM terminal 2T

Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the harness.

- PSP switch terminal and body GND
