If your vehicle stalls when traveling, the DPFE sensor could be the culprit. Located on the firewall, this sensor can be difficult to reach. The DPFE sensor is a zipped black box with two rubber hoses and a three-wire plug on the back. The two hoses lead to the EGR pipe, a 0.5-inch pipe that comes off the driver’s side of the exhaust and goes around the engine under the coil pack.
The DPFE sensor is part of the exhaust gas recirculation system, which filters exhaust gas and reduces emissions. The DPFE monitors pressure changes in the EGR system. When this sensor is malfunctioning, too much exhaust enters the intake manifold, causing poor gas mileage. You can find the DPFE sensor easily by removing the EGR module.
When the DPFE sensor fails, an error code will be generated. The code may indicate a number of different faults, including a partially blocked passage, a faulty EGR valve, or a vacuum leak. The majority of the information about replacing the DPFE sensor can be found in the vehicle’s manual. Please note that the content on this page is accurate to the best of the author’s knowledge. Professional help should be sought if necessary.

Where is the DPFE Sensor Located?
A DPFE sensor is located in the intake manifold, where it responds to the flow of EGR into the engine. If the DPFE sensor is bad, you can check the EGR valve to determine if it is functioning properly. Using a multimeter, check the wire harness and hose for open circuits. A good ground source should be used for this test. Connect a black multimeter lead to the good Ground point on the engine and the negative (-) terminal of the battery. The multimeter should show a reading of 0.9 Volts.
The DPFE sensor is located behind the upper intake manifold near the EGR valve. It is a small, square device that has two vacuum hoses on the bottom and a wire harness on the side. Each make and model of vehicle has its own DPFE sensor location, so consult a repair manual for the specific location on your particular model. To install a new DPFE sensor, follow the procedure described above, but make sure that it fits snugly in the intake hoses.
What are the Symptoms of a Bad DPFE?
There are some common warning signs that indicate that your DPFE sensor is malfunctioning. If the sensor doesn’t send accurate data to the engine computer, your EGR system may not be functioning properly. This could result in reduced power and rough idle. Perfect engine performance is crucial to EPA fuel economy estimates. So, if you see one of these warning signs, you may want to get it replaced.
Your DPFE sensor is located inside the engine and connected to vacuum hoses. If it is clogged, it will likely result in poor fuel economy, poor engine performance, and high engine and transmission temperatures. It can also cause your engine to cough up black smoke and your check engine light to illuminate. You can check your engine’s DPFE sensor by performing the above-mentioned symptoms.
If the check engine light comes on, it is most likely caused by a problem with the EGR system. A bad DPFE sensor may not cause the Check Engine Light to come on. The Check Engine Light is an indication of a problem with the engine, and not the DPFE sensor. Your Ford F150 may have a bad DPFE sensor, so check it out before calling a mechanic.
What is a Ford DPFE?
A DPFE sensor is the component that monitors changes in the pressure within an exhaust gas recirculation (EGR) system. The EGR system sucks back exhaust gas into the motor and re-burns it to reduce pollutants. DPFE sensors are found in Ford vehicles, including the Focus, Ranger, Expedition, Fusion, and Taurus. You can also find them in Lincoln cars.
It’s important to recognize the symptoms of a failing DPFE sensor and how to fix them. Faulty DPFE sensors can result in an uneven idle, poor engine power, and trouble passing emissions tests. Additionally, a faulty DPFE sensor can lead to further air pollution. When you notice a faulty DPFE sensor, get it replaced as soon as possible. It won’t cost more than $150, and a professional installation will take no more than thirty minutes.
The DPFE sensor is located at the plenum where exhaust gases enter the EGR system. The location of this sensor varies by model, but you can check your service manual for a diagram of where the DPFE sensor is located. The DPFE sensor can cost anywhere from $150 to $500 depending on where you live and what tools you have on hand. Despite its complexity, the DPFE sensor is relatively inexpensive, and can be replaced by an owner with basic tools and the right knowledge.
What Causes a DPFE Sensor to Go Bad?
There are several causes of a DPFE sensor’s failure. Some components degrade over time, and it can be expensive to replace them professionally. Fortunately, a DIY project can often be completed in less than 30 minutes. In order to make sure you don’t damage any of the important parts, read on to learn how to replace a DPFE sensor.
The DPFE sensor is located near the EGR valve, which is located behind the upper intake manifold and between the engine and the firewall. This sensor is a small, square-shaped part with two hoses attached on the bottom and a wiring harness on the side. It is responsible for measuring the amount of EGR in the system and sending the data to the PCM.
A faulty DPFE sensor can cause many engine problems, including rough idling and poor engine performance. A faulty DPFE sensor can also cause the EGR valve to stay closed more than it should, which will result in increased engine temperatures and increased emissions of harmful NOx. You can easily test a DPFE sensor by following the instructions in a repair manual.
How Do You Check a Ford DPFE Sensor?
If your DPFE sensor isn’t reading between 0.8 and 1.0 volts, it may be a faulty one. To test this sensor, you should disconnect the vacuum hoses connected to it. While gently pulling on the sensor, check to see if it’s sitting straight. If not, try to remove it by hand and hold the nipples of the sensor to help you pry it out. Then, connect the meter’s black lead to a known good ground. Next, connect the red lead to each plug terminal. Once you’re finished, secure the new DPFE sensor with zip ties or hose clamps. Now, you can start your vehicle and verify all the functions are working properly.
The DPFE sensor is a part of the exhaust system. It helps prevent emissions and ensures that exhaust gases burn completely. Typically, this sensor fails slowly and quietly, but a few signs of a problem can signal a faulty sensor. If this is the case, it’s important to perform this test regularly, as it may be the only way to save the environment’s air.
How Do You Change a DPFE Sensor?
To replace a faulty DPFE sensor, disconnect the electrical connector that connects the DPFE sensor to the EGR valve. The DPFE sensor is a small square that has two vacuum hoses coming out the bottom and a wire harness coming out of the side. The exact location varies from make to make, but it is usually located behind the upper intake manifold. Before you start removing the DPFE sensor, make sure to disconnect the ignition key and battery. Once the wiring harness has been disconnected, connect the new DPFE sensor to the PCM and reconnect the wires to the battery.
If your vehicle fails to pass emissions tests, you may need to replace your DPFE sensor. Faulty DPFE sensors can lead to engine performance problems, including a rough idle and decreased power. They can also cause the EGR valve to stay closed longer than it should, causing increased engine temperature and NOx emissions. If you notice any of these symptoms, it may be time to take your F150 in for an inspection.
Can a DPFE Sensor Cause a Misfire?
You may see a diagnostic code, P0300, for misfire on a Ford F150. The code indicates that a misfire is occurring, either randomly or repeatedly. It does not indicate which cylinder is malfunctioning, and you can usually reset the code and see if it comes back. However, this diagnostic code can also be indicative of another issue. For example, the misfire code may indicate a faulty ignition coil. If you’re unsure of the source of your misfire, it’s best to get your car checked by a mechanic.
Other potential causes for misfire are fuel contamination, cracked EGR tube, and faulty EGR valve. Before tackling these problems, it is important to diagnose your car with a code reader. Using a code reader will help you pinpoint the exact problem and make sure you’re replacing the right part. Alternatively, you can use a misfire monitor to see what’s going on inside your engine.
