The differential pressure feedback exhaust sensor or dpfe sensor is part of the vehicle s exhaust gas recirculation egr system.

Diesel particulate filter pressure sensor a circuit low.

This diagnostic trouble code dtc is a generic powertrain code which means that it applies to all 1996 newer vehicles ford dodge gmc chevrolet mercedes vw etc. Diesel particulate filter dpf the diesel particulate filter dpf is located in the exhaust system under. Diesel particulate filter restriction soot accumulation. Diesel particulate filter pressure sensor a circuit.

The ends of the filter plugged in a checkerboard pattern force the soot containing exhaust to flow through the porous filter walls. It s no secret that as cars and trucks age their value decreases. Not all dpf systems have a parked regeneration feature. The signal of the sensor is not sufficient to determine an optimized timing for regeneration of the dpf.

The sensor monitors and measures the pressure with the egr valve. Check here for special coupons and promotions. Tap off is located before the dpf and one after. 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.
