Installation & Application Notes

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.

Failure Symptoms

An illuminated engine oil pressure warning light is often the first indication of a faulty pressure sensor switch. If ignored, the system may continue to operate with inaccurate pressure data, potentially leading to undetected low-pressure conditions. The ultimate risk is insufficient lubrication, causing accelerated engine wear or component damage.

Installation Tip

Clean the threaded port thoroughly before installation to ensure a good seal and proper electrical connection. Avoid overtightening the sensor, as this can damage the threads or the sensor housing.

Service Note

Inspect the engine oil and oil filter condition during replacement, as these can be contributing factors to pressure-related issues.
