I changed the EGR, and reset the code a few days ago, and it's back again. What could cause this code with a new EGR? | What are the Possible Causes of the P1401 FORD Code? 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)Here’s our process for diagnosing and troubleshooting a P401 trouble code. Our tech scans codes and documents the freeze-frame data to verify the problem and code. Next, we clear the engine and ETC codes in the ECM, and then take your vehicle for a short road test to see if the problem reoccurs.. Any resistance in this control circuit or failure of the EVR can cause a P0401 code. The original DPFE hoses are a special high-temperature hose. These hoses can crack or collapse internally over time due to intense thermal cycling that takes place within the EGR system. Replacement hoses are available in pre-cut sections from NAPA.What is the cost to resolve a P0401 code? Estimated part(s) cost: $50-$300; Estimated labor cost: $100-$400; Estimated total cost: $150-$700; Repair cost will vary across make and model. EGR valves come as either mechanical or electric with the former in the $100 to $150 and the latter in the $250 to $300 range. Sensors will be lower in ...How to Fix a Code P0401 #1 - Check For Additional Codes #2 - Inspect EGR Wiring and Vacuum Lines #3 - Check For Sufficient Vacuum/Voltage #4 - Verify EGR Temperature Sensor Operation #5 - Remove/Clean EGR Valve #6 - Replace EGR Valve/Motor What Does Code P0401 Mean? OBD-II Trouble Code P0401 Description Insufficient EGR FlowHere’s our process for diagnosing and troubleshooting a P401 trouble code.

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)| P0401 FORD code tech notes EGR flow malfunction could be caused by a clogged EGR valve or EGR tube. Before replacing any parts try cleaning the EGR valve, tube, and passages. If the tubes are clean you may have to replace the EGR Pressure sensor to fix the problem. There is a factory service bulletin for the following Ford models:2001 ford escape 6cyl. Code p401 called for a replacement of the egr valve. Replaced egr valve and dpfe sensor. Computer reset itself (finally)after driving it for 328 miles. Check engine light came on again. Same code. Replacement part # for dpfe sensor. Napa 2-22003.P0401 code definition. Exhaust Gas Recirculation Flow Insufficient Detected. What the P0401 code means. P0401 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve is not flowing enough recirculated exhaust gases when it is commanded to open the flow of gases into the intake manifold.P0401 is a common OBDII trouble code that'll pop up in the Ford Econoline. It has to do with the emissions system and stands for: The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the Econoline's EGR system.What is the cost to resolve a P0401 code? Estimated part(s) cost: $50-$300; Estimated labor cost: $100-$400; Estimated total cost: $150-$700; Repair cost will vary across make and model.
