Common questions

What should the differential pressure be on a DPF?

What should the differential pressure be on a DPF?

It should be around 12.6 volts. Consult the manufacturer’s service manual to identify the signal, ground, and 5-volt reference and back-probe the wires.

What is the EGR system on a Ford F350?

The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the F350’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.

How does the EGR pressure feedback sensor work?

When the EGR pressure feedback sensor detects that the pressure is low, it will open up the EGR valve to increase flow, and just the opposite will close the valve if it detects that pressure is too high.

How does the differential pressure feedback exhaust sensor work?

How to Test the DPFE Sensor. The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle’s exhaust gas recirculation (EGR) system. The sensor monitors and measures the pressure with the EGR valve. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time.

How does a delta pressure feedback ( dpfe ) EGR work?

• a Delta Pressure Feedback EGR (DPFE) that measures the change in exhaust pressure before and after a restriction in the exhaust tube that leads up to the EGR valve. When certain driving conditions are met and the computer wants exhaust gas recirculation, it provides a pulsing voltage to the electronic vacuum regulator (EVR).
