MPV ES V6-2.5L DOHC (2001)
Power Steering Pressure Switch: Testing and Inspection
NOTE: Perform the following test 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 PID value or PCM terminal 31 voltage are out of specification, perform the "Circuit Open/Short Inspection".
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
3. Tighten the connector attaching bolt.
Tightening torque
3.0 - 5.4 N.m {30 - 56 kgf.cm, 27 - 48 in.lbf}
4. 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.
