If your vehicle shows emission warning light, abnormal fuel consumption or accelerated acceleration loss, or exhaust NOx exceeding standards, the NOx sensor is aging or failed, causing ECU to inaccurately monitor NOx concentration. When functioning properly, it provides real-time NOx content feedback to the ECU to adjust urea dosing, ensuring SCR system efficiently cleans exhaust and reduces emissions. OEM numbers 5WK97101 / A2C8716660001 / A2C87167601; fits most Euro IV, V and VI diesel vehicles, such as FAW, Dongfeng, and other commercial vehicles. When installing, ensure cleanliness of the sensor hole to prevent debris ingress and secure the connector to avoid loosening and signal errors.
