2894941 — Nitrogen Nox Sensor 2894941 3687334 For Cummins Engine Isx15 Volvo Truck Vnl Vt

This Nitrogen Oxides (NOx) sensor is a critical component of the engine's exhaust aftertreatment system, measuring the level of NOx emissions to optimize the selective catalytic reduction (SCR) system. Manufactured to meet stringent emissions control standards, it provides accurate readings essential for efficient DEF injection, unlike a faulty sensor that can cause incorrect system operation. A failing NOx sensor will typically trigger a check engine light or a specific emissions system warning on the dashboard, often accompanied by a reduction in engine power or increased fuel consumption.

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 of a failing NOx sensor is the illumination of the check engine light or a dedicated emissions warning light on the dashboard. If left unaddressed, the engine control module may enter a reduced power mode (limp mode) to prevent excessive emissions, and fuel economy will likely decrease. Continued operation with a faulty NOx sensor can lead to costly aftertreatment system damage and potential regulatory non-compliance.

Installation Tip

Ensure the exhaust system is completely cool before attempting to remove or install the NOx sensor to avoid burns. Apply anti-seize compound specifically designed for exhaust sensors to the threads before installation to facilitate future removal.

Service Note

When replacing a NOx sensor, it is essential to perform a diagnostic scan to clear any related fault codes and potentially recalibrate the new sensor according to the manufacturer's procedure.
