This is an Oil Pressure Sensor that monitors the engine's oil pressure and transmits this data to the instrument cluster or engine control unit. It is vital for alerting the operator to low oil pressure conditions, which can cause severe engine damage. A faulty sensor may provide inaccurate readings, fail to trigger warnings, or cause the oil pressure warning light to illuminate falsely. This sensor is designed to meet the demanding requirements of heavy-duty truck applications.

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a faulty oil pressure sensor can be an illuminated oil pressure warning light when the engine is running, or the gauge showing incorrect pressure readings. If the sensor fails to detect critically low oil pressure, the engine may run without a warning, leading to rapid internal wear and potential seizure. The ultimate risk is catastrophic engine damage due to insufficient lubrication.
Ensure the engine oil is drained before attempting to remove the old sensor to prevent oil spillage. Apply a small amount of thread sealant to the new sensor's threads, but avoid getting sealant into the sensor's port.
Always check the engine oil level and condition when replacing the oil pressure sensor.
