What does the DPFE sensor measure?
What does the DPFE sensor measure?
The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle’s exhaust gas recirculation (EGR) system. The sensor monitors and measures the pressure with the EGR valve. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time.
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 causes differential pressure feedback electronic ( dpfe ) sensor circuit high?
P1401 FORD Possible Causes 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 Damaged Powertrain Control Module (PCM) What does this mean?
What is the dpfe sensor in an EGR?
The Delta Pressure Feedback in an EGR system is abbreviated as DPFE. It is an electronic sensor responsible for monitoring the number of emissions sent back in the combustion system. It communicates with a powertrain control module to ensure all the gases being sent back are completely burnt.
What does dpfe sensor circuit high P1401 mean?
P1401 FORD | DPFE Sensor Circuit High | The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small
What does P1401 mean on a Ford engine?
P1401 FORD Meaning The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge.
What does the dpfe sensor read on a car?
Regardless of the acronym’s definition, the DPFE Sensor reads changes in the pressure of the EGR system. For those unfamiliar, “EGR” means “Exhaust Gas Recirculation”, and this refers to the process of the system actually sucking exhaust gases back into the engine for re-burn purposes.
How much does it cost to diagnose a P1401 code?
The cost of diagnosing the P1401 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.
