A reading of infinite resistance (open circuit) or zero resistance (short circuit) indicates a defective sensor that requires replacement. A discrepancy between the two readings confirms a faulty sensor rather than an issue with the engine itself.
Testing a Clogged Oil Gallery Sensor for Accurate Diagnosis
If the wiring is damaged, the sensor is bad, or the gallery is clogged, the dashboard light will activate even if the engine oil is perfectly fine. Interpreting the Results and Next Steps.
When oil pressure rises, it moves an internal mechanism that changes resistance or opens a contact. Most modern vehicles use a pressure switch or variable resistance sensor that sits in the engine block, threaded into an oil gallery.
