How to Test an Oil Pressure Sensor?

[LilahFitz]

Remove the oil pressure sensor. Screw the hose connector of the oil pressure gauge into the threaded hole where the oil pressure sensor was installed, and tighten the connector. Place the oil pressure gauge in a location where it will not come into contact with rotating engine components or high-temperature parts. Check for oil leaks at the oil pressure gauge connector. If there is any leakage, turn off the engine and retighten the connector. Allow the engine to reach normal operating temperature, then check the readings on the oil pressure gauge at both idle and 2000 r/min, comparing them with the standard pressure values.
