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

Early indicators of a failing pressure-sensitive module include intermittent or inaccurate pressure readings on the instrument panel, or the illumination of engine warning lights. If left unaddressed, the engine control module may receive incorrect data, leading to suboptimal performance, reduced power, or engine shutdown. In severe cases, incorrect pressure readings could lead to internal engine damage if critical parameters are not maintained.

Installation Tip

Ensure the sensor port threads are clean and free of old sealant or debris before installation to guarantee a proper seal. Avoid using excessive force when threading the sensor, as this can damage the sensor body or the engine block threads.

Service Note

When replacing a pressure sensor, inspect associated wiring harnesses and connectors for any signs of corrosion or damage.
