22303390 — Nitrogen Oxide Nox Sensor 22303390 For Volvo Truck D11 D13 D16 Mack Engine Mp7 Mp8

This Nitrogen Oxide (NOx) sensor monitors the exhaust gas composition, measuring the amount of NOx emitted by the engine to ensure compliance with emissions regulations. Manufactured to meet strict OEM performance and durability standards, it provides accurate readings, unlike a faulty sensor that can lead to incorrect exhaust aftertreatment control. Common symptoms of a failing NOx sensor include illuminated check engine lights, reduced engine power, and increased exhaust emissions.

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

The most common initial symptom is the illumination of the check engine or emissions warning light on the dashboard. If left unaddressed, the engine's performance may degrade, and fuel economy can suffer as the aftertreatment system operates inefficiently. Failure to address NOx sensor issues can lead to costly repairs and potential regulatory non-compliance.

Installation Tip

Ensure the exhaust system is cool before attempting to remove the old sensor, as it can be seized due to heat and corrosion. Use the correct thread sealant if specified by the manufacturer, and avoid cross-threading the new sensor during installation.

Service Note

After replacing a NOx sensor, it is often necessary to perform a sensor calibration or reset procedure using diagnostic equipment to ensure proper system operation.
