POWER STEERING PRESSURE (PSP) SWITCH INSPECTION [LF]

NOTE: Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See Troubleshooting Procedure.)

Continuity Inspection

1. Inspect the following items:
- Power steering fluid amount.
- Power steering-related inspection. (See STEERING LOCATION INDEX.)

2. Disconnect the PSP switch connector.
3. Start the engine.
4. Verify that the continuity between PSP switch terminal A and body ground is as indicated in the table.




- If not as indicated in the table, replace the CPP switch. (See POWER STEERING OIL PUMP DISASSEMBLY/ASSEMBLY.)
- If the monitor item condition/specification (reference) is not within the specification, even though there is no malfunction, perform the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection

1. Disconnect the PCM connector.




2. Inspect the wiring harness for open or short circuit (continuity Inspection).

Open circuit
- If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
- PSP switch terminal A and PCM terminal 2T
