Egr valve is usually located near the throttle body (the thing the accellerator cables go to) and it goes from the exhaust pipe to the throttle body, so anyhting from the upper intake manifold that connects to the exxhaust. It is about the side of a (or a bit smaller than) a snapple Iced tea jar/bottle.

What is the function of the DPFE in a 2003 ford expedition?


Delta Pressure Feedback of EGR (or DPFE) is the difference or change in the EGR system pressure. The DPFE Sensor reads changes in the pressure of the EGR system.

There's a vacuum line coming off the intake manifold to the EGR actuator. The actuator is on the firewall and it's an electric device controlled by the PCM that modulates how much vacuum pressure gets past it. From there, another hose goes to the EGR Valve. Vacuum pressure opens the EGR Valve, allowing exhaust gases to be pulled from the exhaust manifold, past the DPFE tubes, then back into the intake manifold. When gas flows through the EGR tube, the two tubes leading to the DPFE Sensor get pressurized. There's a differential in the pressure, one tube has more pressure than the other one. The DPFE registers the amount of pressure difference and can tell how much exhaust gas is flowing through the EGR system. It tells the PCM how much is flowing, and The PCM uses this reading to control the actuator.

I have a tropubleshooting code of P1405. On a ford Expedition 5.4l. Where do i fine the DPFE sensor (DPFE sensor upstream hose off or plugged.. aaECM detected EGR flow in a negative direction with aan


DPFE sensor failures are VERY COMMON on Ford vehicles. However, clogged EGR ports are also very common on 5.4L Ford engines. The DPFE sensor is located on the left side of the engine. It connects to two silicone rubber hoses that connect to the steel EGR tube coming from the back of the engine to the EGR valve. (See picture of the sensor below)

Another common failure is a DPFE sensor that has melted due to excessive exhaust back-pressure. If you find the DPFE sensor melted, suspect a restricted exhaust. (smashed tailpipe, clogged catalytic converter, etc..)

Check engine light code P0401 98 Ford expedition


OBD-II Trouble Code P0401 - Insufficient EGR Flow

EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR. You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.

A code P0401 most likely means one or more of the following has happened:
The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
There is a blockage in the EGR (tube), most likely carbon buildup
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum

Check it and keep us updated. Hope this helps (remember to rating this free answer).

1997 ford expedition 5.4 reading lean on code scan i changed egr valve and egr pressure valve


Check this thoroughly for vacuum leaks. Ford uses 90 degree elbows that collapse and create major vacuum leaks. This is usually the reason for lean codes and mass air flow sensor codes.

Where is the egr valve position sensor located on a 2002 Ford Taurus SE?


I dont think it has one... there is a sensor on the egr pipe that telsl the computer if the egr is operating or not. Its the PDFE sensor, it looks like a little box with 2 hoses on the egr pipe.

P1401 AND P1311 CODE ON FORD EXPEDITION 2002


P1401 DPFE (Differential Pressure Feedback EGR) circuit high input: This code is in reference to the actual EGR valve monitoring sensor(DPFE). The actual circuit is damaged, thus, producing false negatives.The silicone rubber vacuum lines going to the sensor could also be faulty, as well. I would suggest to inspect the vacuum hoses that run to and from the DPFE sensor. If the hoses are in good shape; Replace the sensor, itself.

You could also check the EGR valve for faults, as well. If you have access to a hand vacuum pump, you can check the EGR passage quite easily with this device. Once you have gathered your pump; Disconnect and plug the vacuum line going to the EGR valve. Connect the vacuum pump to the EGR valve. Start the car and let it idle. Now, apply a simulated vacuum effect with the hand pump to the EGR valve. Your engine should stumble or stall if the passage is open. If it doesn't, the passage is clogged or the diaphragm in the EGR valve is bad. If the passage is open, it's most likely the DPFE sensor.


P1311
Ionization Misfire Detection Module Communication Fault: This code is not a normal ford code. With that said; I would advise to inspect all wiring that is running to the coils on this engine. This code will usually point to a failed coil or coil wire connection. i would also have each coil on this engine tested for their operational value. Check the entire engine harness for pinching or any damage that my be present.

I have a ford explorer sport 2002 and my chek engine light came on it put out a code PO401 do you know what i need to buy


PO401 code means that:
The PCM has determined that there is insufficient flow in the exhaust gas recirculation system. Definition: EGR system fault (Exhaust Gas Recirculation) Probable Causes: a. Blocked passage on EGR system b. Failed EGR Valve c. EGR solenoid faulty d. Failed EGR pressure sensor where applicable e. Failed EGR position sensor where applicable
