OIL PRESSURE SWITCH INSPECTION (AT)

Caution

• Water or foreign material entering the connector can cause poor connections or corrosion. Be sure that water or foreign material do not enter the connector when disconnecting it.

On-Vehicle Inspection

1. Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION.)

2. Remove the battery cover.

3. Disconnect the negative battery cable.

4. Remove the catalytic converter.

(See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

5. Remove the insulator.

6. Disconnect the solenoid valve connector.

7. Inspect for continuity between the following terminals.

• Terminal B and J (oil pressure switch B)

• Terminal A and J (oil pressure switch C)

• Terminal L and J (oil pressure switch F)

– If there is continuity, inspect the wiring harness between the solenoid connector and oil pressure switches. If there are no malfunctions with the harnesses, inspect the oil pressure switches. (See Off-Vehicle Inspection.)

– If there is no continuity, inspect the oil pressure switches for verify the oil pressure switches are no malfunctions. (See Off-Vehicle Inspection.)

8. Connect the solenoid valve connector.

9. Install the insulator.

Tightening torque

8-11 N·m {82-112 kgf·cm, 72-97 in·lbf}

10. Install the catalytic converter.

(See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

11. Connect the negative battery cable.

12. Install the battery cover.

13. Install the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION.)

Off-Vehicle Inspection

1. Remove the oil pressure switch. (See OIL PRESSURE SWITCH REMOVAL/INSTALLATION (AT).)

2. Apply 393-490 kPa {4.0-5.0 kgf/cm², 57-71 psi} of air pressure to the oil pressure switch, and inspect for continuity between the oil pressure switch connector and the oil pressure switch screw.

• If there is no continuity, replace the oil pressure switch. (See OIL PRESSURE SWITCH REMOVAL/INSTALLATION (AT).)

3. Not apply of air pressure to the oil pressure switches, and verify for no continuity between the oil pressure switch connector and the oil pressure switch screw.

• If there is continuity, replace the oil pressure switch. (See OIL PRESSURE SWITCH REMOVAL/INSTALLATION (AT).)

4. Install the oil pressure switch. (See OIL PRESSURE SWITCH REMOVAL/INSTALLATION (AT).)
