What does the DTC code p0401 stand for?
Diagnostic trouble code (DTC) P0401 stands for “Exhaust Gas Recirculation (EGR) Flow Insufficient Detected.” This code means that the computer detects insufficient exhaust gas recirculation (EGR) flow in the system.
What causes code p0401 exhaust EGR flow insufficient?
The EGR passages could be restricted too. The EGR ports in the throttle body clog up very often. Ford:One of the common problems with many Ford vehicles that can cause the trouble code P0401 is a bad or damaged DPFE sensor(DPFE stands for Delta Pressure Feedback EGR).
What is the diagnostic code for exhaust gas?
P0401 is a diagnostic trouble code (DTC) for “Exhaust Gas Recirculation Flow Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What should I do if I Smell exhaust in my car?
There may be a hole in the exhaust pipe, tailpipe, or muffler. You also may have worn down a part of the car interior which is letting the exhaust in. Check the door seals and the rear doors. If carbon monoxide is leaking into your car this is serious as this chemical is highly toxic to humans.

What causes the exhaust gas recirculation to malfunction?
The exhaust gas recirculation (EGR) recirculates small amounts of exhaust back into the combustion chambers of the engine in order to decrease the combustion temperature, thereby reducing the formation of smog-producing nitrogen oxides. EGR valves can malfunction by becoming stuck open or closed due to carbon buildup.
