2001 F150 4.6 EGR Problem

Brand new and my first post. My son has a 2001 Ford F150 4.6. We changed the FDPE sensor around this time last year and it took care of the fuel dumping problem at the time. About a week ago the truck started using gas like crazy and the EGR light coded insufficient flow. We changed the FDPE sensor again but this time there is no change and it is still coding insufficient flow. Any help would be appreciated. Thanks

Dialtone is gaining momentum as a positive member of FTE.
Test the EGR valve by applying a vacuum soruce directly to the egr valve port.
At idle, engine should run rough or die if egr is flowing exhaust gas properly.

If not, remove throttle body and check for blocked egr gas passage behind it. It will probably be caked solid with carbon.

Clean it out, reassemble and retest.

If it really is running rich, this is source of the excess carbon buildup and needs to be fixed also, but that is another story.

There has been a lot of replies about this code, so a search would net you all there is about the fault.
The code is the failure report on "one" test the computer does on the EGR system.
The DPFE is not always the problem.
It's a flow test set up by the computer so the DPFE can see the results and report to the computer.
The total passage, the EGR and all hardware involved, any of which will cause a failure if any part/s fails.
Simple testing wil tell you what is the most likely fault.
The DPFE is the last item when all other tests are good.
I only told you half of it.
Dig out the testing and see what you have.
Good luck.

Thanks for your help

Thanks for the information. I sounds to me like I need to do some carbon cleaning.
