22219283 — 24V Nitrogen Oxide Sensor Voe21984358 Voe22219283 5Wk97371 For Volvo Truck Fh4 Fm4 Fh500 Fm500

This is a 24V Nitrogen Oxide (NOx) sensor, a critical component of the selective catalytic reduction (SCR) system used for emissions control. It is manufactured to precise standards to accurately measure NOx levels in the exhaust, ensuring the SCR system functions correctly, unlike a faulty sensor that may lead to incorrect dosing of Diesel Exhaust Fluid (DEF). Operators may observe a check engine light, a DEF system warning, or reduced engine power if this sensor fails.

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 first indication of a failing NOx sensor is often the illumination of the check engine light or a specific DEF system warning message. If the problem is not addressed, the engine's performance may be progressively reduced, and the vehicle may be prevented from starting after a certain period to enforce emissions compliance. Continued operation with a faulty NOx sensor can lead to excessive DEF consumption or insufficient emissions control.

Installation Tip

Ensure the exhaust system is cool before attempting removal and installation to avoid burns and potential damage to the sensor or exhaust components. When installing the new sensor, apply a small amount of anti-seize compound to the threads, being careful not to get any on the sensor tip.

Service Note

Inspect the Diesel Exhaust Fluid (DEF) lines and injector for clogs or leaks, and check the DEF tank level and quality when replacing the NOx sensor.
