What is the dpfe sensor on Ford p1400?
The system employs an EGR Valve, an Electronic Vacuum Regulator (EVR), and a Delta Pressure Feedback EGR sensor (DPFE). The DPFE Sensor measures EGR flow across an orifice located inside the special EGR Tube.
What to do if your car has code P1401?
How do I fix code P1401 FORD? Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. How much do you know about cars? What does this mean? The cost of diagnosing the P1401 FORD code is 1.0 hour of labor.
How much does it cost to repair a P1401 Ford engine?
The cost of diagnosing the P1401 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. P1401 FORD Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light) P1401 Ford Description
How is the pressure of the EGR valve measured?
When the EGR Valve is open, a pressure differential is created across the orifice (intake manifold pressure vs. exhaust pressure). By design, this difference in pressure is measured by the DPFE sensor in terms of voltage. The DPFE voltage signal output to the PCM is directly proportional to the flow of exhaust gas entering the intake manifold.
What does P1401 mean on the dpfe sensor?
P1401 indicates a problem with the DPFE sensor, which is part of the EGR system. This code is relatively common on Ford engines… This code is relatively common on Ford engines, especially smaller four-cylinder makes.
What should I do if my Ford P1401 code goes bad?
The recommended repair for a P1401 code is to replace the DPFE sensor with a new one. Ford offers an upgraded DPFE sensor for most models (part number 4U7Z-9J460-AA) that is reportedly higher quality than the factory sensor it replaces.
What is the error code for the EGR valve?
As said earlier, the EGR valve has a feedback sensor called the DPFE sensor. When this sensor goes bad or fails, the Error Code P1401 is triggered, along with other related trouble codes, which are usually P0140 variants.
What is the error code for differential pressure feedback sensor?
Table of Contents. Error Code P1401 is defined as DPFE (Differential Pressure Feedback Sensor) Error. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Ford and Hyundai.
