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 erratic or fluctuating speed reading on the instrument panel is an early indicator of a faulty speed sensor. If left unaddressed, this can lead to inconsistent transmission shifting or engine performance issues. The ultimate consequence can be the inability to accurately control vehicle speed or engine RPM, impacting operational safety.

Installation Tip

Ensure the sensor's mounting surface on the transmission or engine block is clean and free of debris before installation. Avoid using excessive force when threading the sensor into its bore.

Service Note

Inspect the wiring harness and connector for damage or corrosion when replacing the speed sensor.
