Sounds like you have a vacuum leak, a problem with the wiring, or a bad PCM. Check wiring for pinched, chafed, pierced, or broken wires. Make sure vacuum supply is good, and not collapsing when the vehicle is running. Beyond that, a trip to the dealer may be in order.

you probably have blocked passages in the intake manifold. remove the egr and check the port for a clog. you can scrape most of the carbon out with a pick or screw driver and then use some spray carbon cleaner in there. also check the metal exhaust line to the egr

silly question, however did you check the air box for nests. it is not uncommon for rodents to climb in and make themselves at home. i would also say to get a maf from ford. check ALL around the engine compartment and underneath for evidence of rodents and their leavings. youll be very suprised what you may find.cheers

1401 egr code


P1401 FORD - DPFE Sensor Circuit High
Faulty Differential Pressure Feedback Electronic (DPFE) sensor
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection. This is not likely the EGR but the EGR pressure sensing valve.

Would a clogged EGR valve cause rough idle in 99 taurus?


"clogged" EGR valve could not cause a poor idle, as it's supposed to be closed at idle. Pinging under acceleration, higher operating temperatures maybe. But it would have to be stuck open (or otherwise open when it's not supposed to be, which includes at idle) to cause a poor idle quality. So, which actual code was this anyway? Because I can't think of any "low pressure" that would relate to the valve itself. It operate on vacuum not pressure. Maybe the pressure sensor, but not the valve. If we had the actual code, maybe someone who knows what's what could clear this up, and save you a lot of money wasted on perfectly good parts being replaced?

Need to find and replace the DPFE-15 sensor. Dealership diagnosed when service engine light came on and saaid this is what needed replacing. Problem is I do not know where to find it on the engine.


Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system is designed to:
  • reintroduce exhaust gas into the combustion cycle.
  • lower combustion temperatures.
  • reduce the formation of oxides or nitrogen (NOX).
The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the following:
  • engine rpm
  • engine vacuum
  • exhaust system back pressure
  • engine coolant temperature
  • air charge temperature
  • throttle position
The EGR valve (EGR valve) (9D475) is vacuum-actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. The EGR system is a differential pressure feedback EGR Sensor system. Differential pressure feedback EGR Sensor is a subsonic closed loop EGR system. The differential pressure feedback EGR system:
  • monitors EGR flow rate by the pressure drop across the metering orifice located in the EGR tube.
  • uses a differential pressure feedback EGR sensor as the feedback device.
  • uses the EGR valve only as a pressure regulator, rather than a flow metering device.
  • controlled pressure is varied by the valve movement using vacuum output of the EGR vacuum regulator solenoid (9J459).
  • allows for a more accurate assessment of EGR flow requirements.

Differential Pressure Feedback EGR Sensor Removal
  1. Disconnect engine control sensor wiring (12A581) from Differential Pressure Feedback EGR Sensor.
  1. Disconnect Differential Pressure Feedback EGR Sensor hoses from EGR valve to exhaust manifold tube (9D477).
  1. Remove retaining nuts or bolts (depending upon application) and EGR Differential Pressure Feedback transducer.
Installation
  1. Follow removal procedure in reverse order.
  1. Tighten retaining nuts or bolts (depending upon application) to 5-7 Nm (45-61 lb-in).

unplug coolant tempurature sensor. if it runs better, then the sensor is your problem. a bad coolant sensor adjusts air to fuel mixture, depending on temp. of engine. it will run to rich and not enough of air if bad. it will also run rough at idle. if check engine light is on get it scanned for the problem code.

    My code reader says p1401 ford exscape


    p 1401 is a code for differential pressure feedback egr circuit high input there is a small square sensor on the engine with a vacuum line here is some info Exhaust Gas Recirculation (EGR) System Monitor” Differential Pressure Feedback EGR
    The Differential Pressure Feedback EGR System Monitor is an on-board strategy designed to test the integrity and flow characteristics of the EGR system. The monitor is activated during EGR system operation and after certain base engine conditions are satisfied. Input from the ECT, IAT, TP and CKP sensors is required to activate the EGR System Monitor. Once activated, the EGR System Monitor will perform each of the tests described below during the engine modes and conditions indicated. Some of the EGR System Monitor tests are also performed during on demand self-test.

    The Differential Pressure Feedback EGR sensor and circuit are continuously tested for opens and shorts. The monitor looks for the Differential Pressure Feedback EGR circuit voltage to exceed the maximum or minimum allowable limits.

    The DTCs associated with this test are DTCs P1400 and P1401.
    The EGR Vacuum Regulator solenoid is continuously tested for opens and shorts. The monitor looks for an EGR Vacuum Regulator circuit voltage that is inconsistent with the EGR Vacuum Regulator circuit commanded output state.
