Oil Pressure Switch Repair Procedures

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 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 air at 50 kPa (0.50 kgf/cm², 7.25 psi) is applied through the oil hole, the switch is operating correctly. Check for air leakage. If air leaks, the diaphragm is damaged. Replace it.
