DTC Description: Notes
WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
The after treatment SCR (selective catalytic reduction) temperature sensor module is a smart device that communicates with the engine control module via the CAN 2 communication lines. The after treatment SCR temperature sensor module performs its own internal diagnostics and reports malfunctions back to the engine control module using the CAN 2 communication lines. The after treatment SCR temperature sensor module is used to measure the after treatment SCR intermediate temperature and after treatment SCR outlet temperature. The temperature probes are permanently attached to the after treatment SCR temperature sensor module and cannot be replaced individually.
