Which is the downstream hose of the dpfe sensor?
Refer to the manual to identify and locate the DPFE sensor, its two hoses, and its wiring. Consult the manual to determine which hose is the downstream hose, as well as the function and color coding of each wire in the DPFE sensor electrical connector for future reference.
How can I check the dpfe sensor circuit?
To check if this is the case, run a piece of steel wire trough the hose to check for obstructions, but take care not to poke holes in the soft material of the hose. Replace the hose if there is any doubt about its condition, or its ability to allow a free flow of exhaust gas through it.
Is the dpfe sensor interchangeable with the EGR valve?
In some cases, the DPFE sensor is treated as being interchangeable with the EGR valve, since it is often argued that the DPFE sensor is a “sort of” position sensor for the EGR valve.
Refer to the manual to identify and locate the DPFE sensor, its two hoses, and its wiring. Consult the manual to determine which hose is the downstream hose, as well as the function and color coding of each wire in the DPFE sensor electrical connector for future reference.
Where does exhaust gas go in a Ford dpfe?
The vacuum pulls up on the diaphragm, lifting the pintle off the pintle seat. With the pintle off its seat, exhaust pressure forces exhaust gas up through the EGR tube, the EGR valve, and into the intake manifold at port 4. On the way up to the EGR valve, the exhaust gas passes through a restriction.
To check if this is the case, run a piece of steel wire trough the hose to check for obstructions, but take care not to poke holes in the soft material of the hose. Replace the hose if there is any doubt about its condition, or its ability to allow a free flow of exhaust gas through it.
How is the dpfe sensor connected to the EGR valve?
On the way up to the EGR valve, the exhaust gas passes through a restriction. The DPFE sensor hoses are connected to ports 1 and 2—before and after the restriction. By comparing and reporting the differences in pressure, the computer can determine exactly how much exhaust gas is flowing through the EGR valve.
