Repair Procedures: Inspection
- Check the continuity between the terminal and the body with an ohmmeter.
If there is no continuity, replace the oil pressure switch.
- Check the continuity between the terminal and the body when the fine wire is pushed.
If there is continuity even when the fine wire is pushed, replace the switch.
- If there is no continuity when a 49.0 kPa (0.5 kg/cm2
, 7.1 psi) vacuum is applied through the oil hole, the switch is operating properly.
Check for air leakage. If air leaks, the diaphragm is broken.
Replace it.
