1.
Check the continuity between the terminal and the body with an ohmmeter.
If there is no continuity, replace the oil pressure switch.


2.
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.
3.
If there is no continuity when a 50kPa (0.50kgf/cm?, 7.25psi) is applied through the oil hole, the switch is operaing properly.
Check for air leakage. If air leaks, the diaphragm is broken. Replace it.
