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 Diesel Particulate Filter (DPF) temperature sensor module is a smart device that communicates with the Engine Control Module (ECM) via CAN communication lines. The after treatment DPF temperature sensor module performs its own internal diagnostics and reports malfunctions back to the ECM using CAN data lines. The after treatment DPF temperature sensor module is used to measure the after treatment diesel oxidation catalyst intake temperature, after treatment DPF intake temperature, and after treatment DPF outlet temperature. The temperature probes are permanently attached to the after treatment DPF temperature sensor module and cannot be replaced individually.
