Dpfe sensor broke in the REF tube

Hi, I have a ford taurus 2000 3.0 lt, the dpfe broke in the ref tube, but I disconeted the vacuum hose and now I don't know where connect the vacuum hose, the metal tube have 2 vacuum sockets, and if I connect the vacuum hoses in different sockets would have a problem?, the dpfe sensor have 2 marks these are "REF" and "HI", please explain.

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.

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.

WERES THE DPFE VALUE LOCATION ON 2002 MUSTANG


the sensor is located near the left side exhaust manifold , it has 2 tubes going to it(REF and HI). the values are read with a scanner on the EGRDPFE pid, the voltage can be from 0 to 5 volts. the voltage should be 1.10 +/- .25 volts with the key on and engine off.

Rusted ERG Valve unit on 1995 F150 How to remove.


Disconnect the negative battery terminal. Disconnect the wiring connectors to the air cleaner, Mass Air Flow sensor, EGR vacuum solenoid, and DPFE sensor. Remove the air intake assembly (up to the throttle body). There are two vacuum lines from the EGR vacuum solenoid, find where they reach the EGR valve and the intake manifold, disconnect them at these points. There is a rubber hose coming from the firewall to the top of the engine, disconnect this and push it aside. Remove the nut directly below this hose (this nut holds the bracket that the DPFE and EGR vacuum solenoid are mounted to). Follow the mounting bracket around and remove the smaller nut holding it on. Have some tape ready to mark two hoses. Make a note of which hose is the "Hi" and "Ref" on the DPFE sensor and remove them. Remove the DPFE/EGR vacuum solenoid assembly. Congratulations, now you have access to the EGR valve!!

hoping help you!

Where is the dpfe sensor located on the 2000 ford taurus?


I had to replace the dpfe sensor on my 2000 Ford Explorer and they should be the same.
Mine was located on the left side of the engine (facing the engine with the hood up) above the valve cover. It will have two 3/8" vacuum lines going into it and a plug ended cable. Very simple to replace.

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.

Where is the DPFE Sensor located on a 2003 Ford Taurus 3.0 L 24V engine? Husband can't locate it! Can't find diagram for 2003 Taurus.


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.

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
