SOURCE: Where is the EGR pressure sensor

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.

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..)

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).

I can't find the location of the DPFE (EGR pressure sensor). I've already replaced the solenoid, but can't find this sensor anywhere.


Usually mounted on driver side,on a bracket over exhaust manifold or on a bracket on intake manifold. One of the 2 hoses that attach to it goes directly to egr valve. If you still cant locate it follow hose from egr valve it ends at sensor.

p0401 egr flow insufficient. p0171 system to lean ( bank 1 ). p0174 system to lean ( bank 2 ). common problems that trigger p0401--
  • Restriction in the EGR passages, usually caused by carbon buildup
  • The EGR Valve is defective
  • Lack of proper vacuum or electrical signal to the EGR valve
  • Malfunctioning EGR Vacuum supply solenoid
  • Lack of proper EGR system feedback to the computer from the:
    • Manifold Absolute Pressure Sensor (MAP)
    • Differential EGR Pressure Feedback Sensor (DPFE)
    • EGR Valve Position Sensor (EVP)
    • EGR Temperature Sensor - p0174--
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling also
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure p0171- and p0174 are about the same.

Need location of the erg sensor 2000 ford ranger


The egr valve has two sensors. One is an EGR position sensor which is physically attached to the EGR valve. The other sensor is the DPFE (Delta Pressure Feedback EGR) sensor, commonly called the EGR pressure sensor. It's location varies depending on the engine you have. You can fine this sensor by following the vacuum hose on the EGR valve. It will be with in inches of the EGR valve. The sensor will be black (plastic) or silver (metal), have two or three vacuum ports and an electrical connection on it.

The vacuum pressure sensor is a high failure item on fords. Any Ford parts department will have one in stock, as well as some aftermarket parts stores.

The new sensor may not look exactly the same as the old part, but will have all the hook ups as the old one. You may also need to replace the vacuum hose to the sensor as well

Location of the egr sensor on 2000 ford ranger


The EGR pressure sensor is located within inches of the EGR valve. The exact location varies depending on the engine (2.5L, 3.0L or 4.0L). It is usually attached to the upper intake manifold with two small bolts.
