I have to put thus little bit of info in here. I just had to deal with an 02 Taurus that would not start. Managed to get it to start by holding the gas pedal to the floor and when it finally fired up it blew the DPFE hose off. After a while of it sitting in the garage I decided I would just keep the gas floored and after a few seconds it came around. My suspicion is that because this car only runs for a few minutes at a time, moisture accumulated in the CAT and froze when temperatures got into the single digits. My conclusion is make sure the vehicle get to operating temperature during cold weather to prevent exhaust freeze-up.

SOURCE: Where is the DPFE Sensor located on a 2003 Ford

That is the (Differential Pressure Feedback Exhaust) - e.g. EGR Valve. You shouldn't have any trouble finding it. There is usually a metal tube from the exhaust manifold going to it,as well as one or two vacuum hoses.
It has to also, direct exhaust gas into the intake,so there is your key.

First off, EGR valves seldom fail. Yours probably had nothing wrong with it in the first place. 
DPFE sensors, OTOH, have been a problem for Ford for years. Best results have been obtained with the upgraded Ford replacement. 
Make certain the hoses to the DPFE sensor did not get reversed and are not clogged if you have the non-plug-on version. If the upstream hose is getting blown off or is over-pressurized, clogged cats could be the issue.  
Check the Vacuum line at the EGR valve for vacuum at idle and while reving the throttle. It should not have and vacuum while the vehicle is not in motion. 

It should not have any vacuum while the vehicle is not in motion. 
If it does, you'll have EGR flow at the wrong time which usually causes idle problems and low speed stumbling/misfires. EVR solenoid is either dirty or sticking open. Try popping the cap off and cleaning the filter element and the top of the valve with compressed air. 
It takes a minimum of two drive cycles in which OBDII runs the EGR test for it to turn on the MIL if there are failures.

When the code is cleared typically you have to run through a specific cycle. With Ford a normal driving can take a couple of days to a week or more. There is page that lists the cycle and you can run through it about 45 minutes

SOURCE: 99 Taurus SE where do I

Do yourself a favor and do NOT buy one from the parts Store. buy it from the dealer. It has hoses attached to the EGR pipe, so its easy to find.

Surging problem 2007 ford taurus 3.0


Tests/Procedures: 1. Unplug the mass air flow sensor and see if the concern is gone or improved. If so, suspect mass air flow sensor or circuit problem.

2. Unplug the alternator and see if concern is gone, if so, suspect the alternator or its circuits.

3. Unplug the camshaft position sensor and see if concern is gone, if so, suspect cam sensor/synchronizer fault or incorrectly installed synchronizer.

4. Unplug the DPFE sensor and see if concern is resolved, if so, suspect shorted DPFE sensor.

5. Check torque converter command during concern, make sure it is not being commanded on during surge.

6. Use lab scope to check crankshaft position signal during concern and ensure the signal is not dropping off.

Replace P1401 DPFE Sensor circuit


The P1401 code could be for anything Egr related. Usually it is a defective DPFE (differential pressure feedback Exhaust) But, it can also be caused by a defective EGR valve or EVR (Exhaust Valve Regulator) solenoid/switch. --or an air leak at any part of the system including the silicone hoses that feed the DPFE/

Code P1405


I have copied the entire description for the code.
Let me know if you need more info. You may need a shop to take a look at the system.

P1405 Ford Description
The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge. The resultant diluted air/fuel mixture (i.e., less oxygen per cubic foot) burns cooler and combustion chamber temperatures are reduced accordingly, thereby lowering NOx emissions.
The Ford DPFE/EGR system is controlled by the Powertrain Control Module (PCM). The system employs an EGR Valve, an Electronic Vacuum Regulator (EVR), and a Delta Pressure Feedback EGR sensor (DPFE).
The DPFE Sensor measures EGR flow across an orifice located inside the special EGR Tube. The orifice is positioned between two hose ports coming off the tube which are connected to the DPFE sensor with special heat-resistant hoses. When the EGR Valve is open, a pressure differential is created across the orifice (intake manifold pressure vs. exhaust pressure). By design, this difference in pressure is measured by the DPFE sensor in terms of voltage. The DPFE voltage signal output to the PCM is directly proportional to the flow of exhaust gas entering the intake manifold.

Two lines in center back part of the engine that are not hooked to any thing but are blowing air.. where do i hook these up at


If you are talking about two hoses that connect to two small metal tubes that protrude from a larger metal pipe, they are the hoses that are supposed to connect to your Delta Pressure Feedback EGR Sensor. (DPFE) Your DPFE sensor is most likely burned up if you have the black plastic sensor. You should check for exhaust resrictions before replacing the sensor because a restricted exhaust will only burn up the new sensor as well.

The error code P1401 comes up on my Ford Taurus SE 2002. Can you tell me what it stands for and how to fix the problem?


P1401 - DPFE EGR CIRCUIT HIGH INPUT

Your DPFE is no good hate to say but probably was your proplem the whole time none of the other parts not needed except the fuel filter and pcv good PM stuff there. The DPFE is either going to be a silver or black box around where the egr valve is. be sure not to get the hoses crossed when putting it back on.

Keep us updated.

Do you mean "DPFE"? DPFE stands for Delta Pressure Feedback EGR sensor. It is the sensor that tells your onboard computer whether the EGR Valve is opening up when it is told (by the computer) to do so. It has 2 hoses made of high temperature silicone that connect to two small metal tubes that protrude from the larger metal tube that connects the EGR Valve to the exhaust maifold. Sometimes the high temperature exhaust gasses will burn the DPFE sensor nipples if the vehicle is equipped with the black plastic DPFE sensor. This is sometimes caused by a restriction in the exhaust system such as a bent pipe or a clogged catalytic converter. In such cases, replacement of the DPFE sensor alone will result in a repeat repair.
If your vehicle has a build date prior to May 2002. there is a Technical Service Bulletin (TSB) pertaining to your DPFE sensor - I would recommend having it checked out by a professional.

Here is a list of possible causes for a PO401, hope this helps.

  • DPFE sensor signal circuit is shorted to ground
  • DPFE sensor VREF circuit is open between sensor and PCM
  • DPFE sensor downstream hose off or plugged
  • DPFE sensor hoses both off, loose or damaged
  • DPFE sensor hoses connected wrong (reversed)
  • EGR orifice tube is damaged or restricted
  • PCM has failed

P0401. P0133, P1131- emmision test


Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

Dpfe sensor broke in the REF tube


One hose is reference the other is pressure, the hoses are different sizes, do you have the factory high-temp silicone hoses required? they are different sizes so you can't mix them up, vacuum hose will burn up in short order, the failure of this sensor is almost always caused by excessive exhaust back pressure, you may have a cat converter starting to plug up.
