SOURCE: Ford F250 EGR problem

The EGR valve (Exhaust Gas Recirculator) provides a path from ******** to nose of your engine, returning some of the exhaust fumes to the intake to supposedly improve tailpipe emissions.
Uh huh, I agree. Seems like a stupid idea and each car I have cheated (that couldn't tell I was cheating) has gained a little on gas mileage but never as much as 10%.
Your Ford apparently has a sensor to rat you out if you cheat it so the quantity of fumes isn't satisfying that sensor.
This could mean that the EGR is clogged (it's a small hole passing dirty exhaust fumes), failed, or the vacuum line that controls it is cracked or otherwise broken.

SOURCE: got a code 401 EGR insufficient flow. so i changed

Your problem may be with another component of the EGR system. It is the Delta Pressure Feedback EGR sensor and it is know to have problems. The sensor is connected to the EGR valve by the two lines coming off it. If you do a image search for DPFE Sensors on your make and model you can get an idea what it look for. It may be tucked back behind the intake and firewall. Also check all the hoses connected to it. A vacuum leak could aslo be at fault.
Because Ford has had a lot of problems with these, it is possible that it may even be under a recall so check with a ford dealer before spending any of your own money.
Hope this helps.

Check my profile page and follow the steps listed in my Tips and Tricks for P0401, once the housing is claen reset the light and see if trouble returns if it does, I suggest you replace the sensor, the sensor is located on the left hand side of the engine in front of the EGR valve.

SOURCE: have a po405 code on a 02 impala, said its a egr

In Hopes the info BELOW will Help, And Also the Mass Air Flow Sensor is A Totaly Different Sensor (MAF) The EGR Valve Code you are asking About is More Related to the Exhaust Gas that the EGR Valve is Allowing to Flow Past Its Self. I can tell you that From My Own Experience that EGR Valves Get Dirty More than they Fail and Require a Simple Removal and Cleaning of Carbon Buildup. This is after the Procedure Below is Performed.

The powertrain control module (PCM) monitors the exhaust gas recirculation (EGR) valve pintle position input to ensure that the valve responds properly to commands from the PCM and to detect a fault if the pintle position sensor circuit is open or shorted. If the PCM detect an excessively low EGR Position sensor signal voltage, this diagnostic trouble code (DTC) will set.

The system voltage is greater than 10 volts .


  • The EGR Position sensor is less than 0.14 volts at any time.
  • The condition is present for more than 20 seconds .
  • The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle in which the diagnostic runs and fails.
  • The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
  • The PCM disables the EGR valve for the ignition cycle.

I have a Ford F-150 xlt 4.6 with a p0401 code.

code p 0401 refers to exhaust gas recirculation (EGR) system---insufficient flow detected==== causes ---hose leak/blockage, basic setting not carried our (if applicable)---wiring---EGR valve ---EGR solenoid ---ECM
when you have done everything make sure that you use a scan tool to reset the ECM
Items that you haven't mentioned are wiring and substituting the ecm with a known operational one
bad wiring and connections / ground , broken in side the insulation may cause the problem as well

Replace the EGR valve reset error code and now i get error code of p1407 what do i do now

The most likely cause of this code is a DPFE (differential pressure feedback EGR sensor).

The code 1407 indacates low or no EGR valve flow, this is normally caused by carbon build up in the passage in the intake where the valve mounts. Click over pic to see attachment...


Hope this helps.

I have four codes. P0136, P0141, P0171, P0401.

p0136 and p0141 are o2 sensors and p0401 is a egr flow and the p0171 means its running lean on low bank 1

Ford has problems with the DPFE sensors that has to do with the EGR. its just a code that points you in the direction of the problem. you could have a bad DPFE or egr or just a simple clogged hose. there should be 2 hoses on these f150s the only way to tell is by checking hoses otherwise you need more tools to check these things. a vacuum test on the DPFE sensor to see if it reacts.

the other code is an O2 sensor code. heater problem. could be different problems or a bad O2 can cause a rich condition cause low fuel mileage and also cause the EGR system to clogg over time.
I dont knwo what else to help you with because its one of those things that just needs to be looked at in person. your best bet is check the DPFE hoses. should be near EGR and look for rubber hoses connecter to a sensor. should have 2 hoses connected to it. Google a pic of one so you knwo what they look like.
Good luck
