Where is the ERG valve located on a 2001 F150 and how difficult is it to replace.

Hi and welcome to the forum

Why are you replacing the EGR valve? They very rarely fail.

It is on the front of the intake manifold, has the EGR pipe from the exhaust manifold going to it and 2 bolts hold it to the intake.

 

My service engine light came on and the guy at autozone read it as egr flow insufficient and suggested it might be the valve.

 

I'm assuming he got a P0401 code which is the most common.
The usual fix is to replace the DPFE sensor which is very easy.
Ford extended the warranty on them because it's such a common problem so you might want to call your dealer and ask them about it.

 

Thank you for the info.

 

Let us know what you find out

 

It was indeed the DPFE sensor and my local Ford dealership replaced it at no cost. The warranty was extended to 5 years or 60000 miles.
Thanks again for the help. Great website!!!!!

 

You're welcome
