The NOx sensor for Volvo trucks is an essential component in monitoring and controlling nitrogen oxides (NOx) emissions produced by engines. It is compatible with numerous Volvo models, including 7422827993, 22219283, 22315990, 22827993, 21984358, 201567736, 21387788, 20873395, 20873117, 20751663, 21567736, 85023781, 85029781.

This sensor is responsible for measuring the concentrations of NOx in the exhaust gases, contributing to the optimization of the selective catalytic reduction (SCR) system operation. By keeping emissions within pollution standards, the NOx sensor ensures optimal performance and regulatory compliance.

The image shows a NOx sensor with a long and flexible cable, adaptable for various engine configurations. The cable length is approximately 34 cm, while the sensor itself is about 11 cm long, according to the ruler shown in the image.
