20873395 — Nitrogen Oxide Sensor Voe20873395 20873395 For Volvo Truck Fl Fe Fh Fm

This Nitrogen Oxide (NOx) Sensor is integral to your Volvo truck's exhaust aftertreatment system, accurately measuring NOx levels to ensure compliance with emissions standards. It functions by analyzing exhaust gases, providing critical data to the engine control module for optimal DEF injection and catalyst performance, unlike a degraded sensor that yields inaccurate readings. Operators might observe a lit check engine light, reduced engine power, or increased exhaust emissions when this sensor malfunctions.

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

The initial symptom of a failing NOx sensor is often an illuminated check engine or emissions warning light. If ignored, the engine control unit may reduce power output to protect the emissions system, and exhaust emissions will increase. Persistent failure can lead to failed emissions tests and potential damage to the catalytic converter.

Installation Tip

Ensure the exhaust system is cool before attempting to remove the old sensor, and apply anti-seize compound to the threads of the new sensor before installation. Avoid cross-threading the sensor into the exhaust pipe.

Service Note

Inspect the Diesel Exhaust Fluid (DEF) system lines and injector for any signs of blockage or leakage when replacing the NOx sensor.
