The Diesel Particulate Filter (DPF) differential pressure sensor is located on the end of the transmission. The sensor is located on a bracket which is attached to the end of the transmission casing.

The differential pressure sensor is used by the DPF software in the Powertrain Control Module (PCM) to monitor the condition of the DPF. Two pipe connections on the sensor are connected by pipes to the inlet and outlet ends of the DPF. The pipes allow the sensor to measure the inlet and outlet pressures of the DPF. By measuring the pressure difference between the DPF inlet and outlet and the DPF temperature, the DPF software can determine if the DPF is becoming blocked and requires regeneration. For additional information, refer to: DIESEL PARTICULATE FILTER - SYSTEM OPERATION AND COMPONENT DESCRIPTION

The DPF software performs the following checks using the DPF differential pressure sensor:
