This is an oil pressure switch sensor, which monitors and reports the engine's oil pressure to the control system or dashboard gauge. It is manufactured to precise specifications, ensuring accurate readings and timely warnings, unlike a faulty sensor that may provide incorrect pressure data or fail to activate. Operators might observe a fluctuating or absent oil pressure warning light, or an inaccurate oil pressure reading on the gauge when this sensor malfunctions.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing oil pressure switch is an unreliable oil pressure warning light, which may flicker, stay on constantly, or fail to illuminate when pressure is low. If ignored, the system may not warn the operator of critical low oil pressure, potentially leading to severe engine damage. Continued operation without accurate oil pressure monitoring risks catastrophic engine failure due to insufficient lubrication.
Ensure the engine oil is drained or the oil pan is protected to prevent oil spillage during sensor removal and installation. Do not overtighten the sensor, as this can damage the threads in the engine block.
Check the engine oil level and condition, and inspect the oil pump for proper function when replacing the oil pressure switch sensor.
