Oil Pressure Switch Repair Procedures

Removal and Installation

1. 1
   Remove the under cover.
2. 2
   Remove the oil drain plug and drain the oil into a container.
3. 3
   Remove the oil pressure switch (A).

   Tightening torque: 7.8 ~ 11.7 N·m

   

4. 4
   Install in the reverse order of removal.

Inspection

1. 1
   Using an ohmmeter, check continuity between the terminal and the body. If there is no continuity, replace the oil pressure sensor.

   

2. 2
   Check the continuity between the terminal and the body while pressing the thin wire. If there is continuity even when the thin wire is pressed, replace the switch.

   

3. 3
   If there is no continuity when a pressure of 49.0 kPa (0.5 kgf/cm², 7.1 psi) is applied through the oil port, the switch is operating normally. Check for air leakage. If air leaks, the diaphragm is damaged. Replace it.
