Oil pressure sensor — checking technical condition (Hyundai Tucson LM)

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



2. Check for continuity between the terminal and the housing by inserting a thin wire into the sensor. If continuity is present, replace the sensor.

3. If there is no continuity when applying 50 kPa pressure through the oil hole, the sensor is working normally. Perform an air leak test. Air leakage indicates damage to the diaphragm. Replace it.
