It sounds like the iat sensor "intake air temperature" sensor. When its cold it enriches the mixture.

2002 ford escape starts but wont stay running unless the foot is kept on the pedal. took it to a shop and had a diagnostic test on it. It's saying there is nothing wrong. Mechanic said it must be


Computers rarely fail. The diagnostic would not show anything wrong unless a trouble code is set UNLESS the diagnostic used live data vieew. Most shops dont do that . So at what RPM does it not die? How many miles are on it? Ford uses something called an idle air speed motor. They are prone to fouling.

I would check fuel pressure. Also vaccum leaks could do that.

Exhaust gas recirculation flow insufficient detected.
Maybe you got a bad DPFE sensor, or the pintel inside the egr valve is not opening all the way causing the insufficient flow.

Diagnostic trouble code po401


The p0401 indicates a lack of egr flow. The DPFE sensor (ford basic part number 9J460) is the most common cause of this code. Call a ford dealer for a price and ask if your vehicle is covered under any emissions recall or program for p0401.

I have check engine light on, trouble code p0401, how can I fix it. I'll appreciate. Thank's


P0401 = Exhaust Gas Recirculation, insufficient flow.

I would start with testing the EGR valve and checking the source line for a vacuum leak. EGR may need to be cleaned.

Idle speed


From what I can tell with the info I have It has the sound of the IAC it messing up and this is a pretty common problem sometimes you can remove it and clean it but you will need to replace it in the near future.Iac stands for Idle air control
Jim

on the other user the first thing you must do is fix the vacuum leak then check the code and if it is a P0401 or so this is caused by the DPFE and it will need replaced it too is a fairly common problem and will cause alot of different drivability concerns.DPFE stands for delta pressure feedback sensor
