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

An illuminated check engine light or reduced engine performance, often accompanied by increased exhaust emissions, are common initial indicators of a faulty NOx sensor. Continued operation with a failed sensor can lead to the engine entering a reduced power mode or failing emissions tests.

Installation Tip

Ensure the threads are clean and free of any sealant before screwing the sensor into the exhaust pipe. Do not apply any lubricants to the sensor threads unless specifically instructed by the service manual.

Service Note

Inspect the exhaust system for leaks and check the Diesel Particulate Filter (DPF) status when replacing a NOx sensor.
