Where is the dpfe sensor on my car?
Locate the DPFE sensor, which is near the EGR valve, behind the upper intake manifold, between the firewall and engine. The sensor is a small square with two vacuum hoses on the bottom and a wire harness coming out from the side. The location will vary slightly from make and model. Check your repair manual for exact location…
Is the dpfe sensor called delta pressure feedback of EGR?
As we just mentioned the name, the DPFE sensor is called the Delta Pressure Feedback of EGR. We will talk about EGR later. The DPFE sensor is one of the components of your engine that is there to monitor all the air that is going back in the air intake from the exhaust. Yes, you heard it correct.
What should the volts be on a Ford dpfe?
Ford DPFE sensors should read between .45 and .55 volts. All other makes should read between .8 and 1.0 volts. If the sensor is not within the appropriate range, the sensor is faulty and should be replaced. Johnathan Cronk is a freelance writer and began writing at the age of 18.
What kind of sensor does a Ford F-150 have?
Ford often uses the DPFE sensor for its various vehicle models. The most common car model is probably the F-150. EGR, which stands for “ Exhaust gas recirculation “, is a mechanism that controls exactly what the name suggests. The EGR system consists of a valve that controls the exhaust air returning to the engine.

How is the dpfe sensor connected to the EGR valve?
On the way up to the EGR valve, the exhaust gas passes through a restriction. The DPFE sensor hoses are connected to ports 1 and 2—before and after the restriction. By comparing and reporting the differences in pressure, the computer can determine exactly how much exhaust gas is flowing through the EGR valve.

Why is my Ford dpfe not working properly?
Unfortunately, Ford didn’t give enough consideration to the impact of corrosion inside the DPFE, and that’s what causes most of the EGR related problems. Do it yourselfers and professional technicans make an all-too-common mistake if they automatically replace the EGR valve when they see an EGR related code.
Where are the fuse panels on a Mercury Grand Marquis?
Here you will find fuse box diagrams of Mercury Grand Marquis 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 and 2011, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.
When did the Mercury Grand Marquis come out?
In this article, we consider the fourth-generation Mercury Grand Marquis, produced from 2003 to 2011.
What does dpfe stand for in a car?
“DPFE” means “Differential Pressure Feedback of EGR”. It’s also referred to as “Delta Pressure Feedback of EGR”, with ‘Delta’ meaning “difference” or “change”. Regardless of the acronym’s definition, the DPFE Sensor reads changes in the pressure of the EGR system.
What is the EGR valve on a Toyota Land Cruiser?
They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401 is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Toyota Land Cruiser or not).
What causes the p0401 code on a Toyota Land Cruiser?
Diagnosing what is causing the P0401 code in the Land Cruiser is typically not very tricky. Here are the most common causes: Blocked EGR Tube– The tube that carries the exhaust gases back to the motor may clog up over time. Alternatively, it can become bent or kinked.
What are the three parts of the EGR system?
There are three main parts of the Land Cruiser’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Toyota Land Cruiser or not).
