Installation & Application Notes

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.

Failure Symptoms

The first sign of failure is often an illuminated oil pressure warning light on the instrument panel. If left unaddressed, the engine control module may receive incorrect data, leading to reduced engine performance or unexpected shutdowns. Continued operation with a faulty sensor risks severe engine damage due to inadequate lubrication.

Installation Tip

Clean the threaded port thoroughly to remove any old sealant or debris before installation. Avoid over-tightening the sensor, as this can damage the threads or the sensor housing.

Service Note

Inspect the engine oil level and condition, and check the wiring harness for any signs of damage or corrosion.
