CONSTRUCTION
The differential pressure sensor assembly measures the pressure differences between before and after the DPF catalyst with PM in order to detect clogging.
The sensor is mounted on the cowl, where the effects of vibration are minimal. The DPF catalyst and the sensor are connected with pipes and hoses.
