SOURCE: how do you locate the egr pressure sensor in 2003 mercury grand marquis?

First you need to know what to look for. Here's a link to a auto part web site: http://www.autopartswarehouse.com/details/QQMercuryQQGrand_MarquisQQMotorcraftQQEGR_ValveQQ20032011QQMICX2060.html

The EGR valve takes exhaust gases and inserts them into the intake. Generally the EGR is near the center of the engine toward the back. It should be connected to the intake manifold and a pipe that comes from the exhaust manifold. It's not terribly difficult to change.

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.

Egr sensor blew dont know where to put the new one


This sounds like a clogged catalytic converter. When this happens, the exhaust gases build up in the manifold and before the catalyst. It is very common for the delta pressure feedback sensor hoses to blow off the tubes. If you have access to any tools, you can remove the oxygen sensor and install a backpressure gauge to verify this issue. If you have more than 5lbs, you have excessive back pressure, caused by an exhaust restriction.

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.

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.

Egr vacuum solenoid


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, CHT, 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.
  1. 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.
  1. 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.

    The DTC associated with this test is DTC P1409.
  1. The test for a stuck open EGR valve or EGR flow at idle is continuously performed whenever at idle (TP sensor indicating closed throttle). The monitor compares the Differential Pressure Feedback EGR circuit voltage at idle to the Differential Pressure Feedback EGR circuit voltage stored during key on engine off to determine if EGR flow is present at idle.

    The DTC associated with this test is DTC P0402.
  1. The differential pressure feedback EGR sensor upstream hose is tested once per drive cycle for disconnect and plugging. The test is performed with EGR valve closed and during a period of acceleration. The PCM will momentarily command the EGR valve closed. The monitor looks for the differential pressure feedback EGR sensor voltage to be inconsistent for a no flow voltage. A voltage increase or decrease during acceleration while the EGR valve is closed may indicate a fault with the signal hose during this test.

    The DTC associated with this test is DTC P1405.
  1. The EGR flow rate test is performed during a steady state when engine speed and load are moderate and EGR vacuum regulator duty cycle is high. The monitor compares the actual Differential Pressure Feedback EGR circuit voltage to a desired EGR flow voltage for that state to determine if EGR flow rate is acceptable or insufficient. This is a system test and may trigger a DTC for any fault causing the EGR system to fail.

    The DTC associated with this test is DTC P0401. DTC P1408 is similar to P0401 but performed during KOER Self-Test conditions.
  1. The MIL is activated after one of the above tests fails on two consecutive drive cycles.
0a01005.gif EGR Vacuum Regulator Solenoid The EGR vacuum regulator solenoid (Figure 88) is an electromagnetic device which is used to regulate the vacuum supply to the EGR valve. The solenoid contains a coil which magnetically controls the position of a disc to regulate the vacuum. As the duty cycle to the coil increases, the vacuum signal passed through the solenoid to the EGR valve also increases. Vacuum not directed to the EGR valve is vented through the solenoid vent to atmosphere. Note that at 0% duty cycle (no electrical signal applied), the EGR vacuum regulator solenoid allows some vacuum to pass, but not enough to open the EGR valve.

Exhaust Gas Recirculation (EGR) Vacuum Regulator Solenoid Removal and Installation
  1. Disconnect the battery ground cable (14301). For additional information, refer to Section 414-01 .
  1. Disconnect the vacuum hoses and the EVR solenoid electrical connector.
  1. Remove the two nuts and the EVR solenoid (9J459).
From the looks of the rubber mounting, I would say it's mounted on the cowl (firewall) on the passenger side in the engine compartment.

Please rate as fixya if this helps. Thanks
