OIP Pressure Switch

WARNING: This page is about a different variant/trim than selected.

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 50 kPa (7psi) 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.
