Diesel Particulate Filter Differential Pressure Sensor

The ends of the filter plugged in a checkerboard pattern force the soot containing exhaust to flow through the porous filter walls.

Diesel particulate filter differential pressure sensor.

The most common diesel particulate filters in widespread use are cellular ceramic honeycomb filters with channels that are plugged at alternating ends as shown in figure 1. Differential pressure sensor delta p for particulate filter applications the pressure sensor described underneath is mainly used to monitor the soot loading of a particulate filter on a diesel engine or gas turbine. The dpf differential pressure sensor detects the difference between the exhaust pressure upstream and downstream of the diesel particulate filter by means of the exhaust pressure sampling pipes upstream and downstream of the dpf. When a code p244b is stored you may assume that the powertrain control module pcm has detected an input signal from the circuit of the diesel particulate filter dpf pressure sensor indicating that differential pressure is too high.

The temperature sensor upstream of dpf monitors exhaust temperature during regeneration. Raney s info toll free. 352 789 6701 store location 3030 w silver springs blvd ocala fl 34475 exit 352 off i 75 visit our store hours of operation customer service hours.
