When a Cummins 12V engine shows obvious power loss and elevated fuel consumption, along with the engine fault light (codes such as P2201 or P2202) on the dashboard, this typically indicates NOx sensor aging or failure, unable to accurately monitor NOx concentrations in exhaust. The sensor normally reports NOx data to the ECU to control DEF injection and ensure emissions compliance and optimal combustion. This product is a direct replacement compatible with OEM numbers 2872946, 4326874, 5WK96741, suitable for Cummins ISX, ISL, ISM and other 12V electronic diesel engines. Installation must be done with the power off, avoid moisture or oil on connectors; tighten torque to 35-45 N·m; after installation, use a diagnostic tool to clear historic fault codes and perform sensor self-learning.
