Where is the DPFE sensor and the EGR valve located on an 03 4.0 SOHC? Ive looked all over and I cant find it.

 

A 2003 4.0L has neither. Lucky you.

 

agreed!

 

really? wtf how come I found an EGR valve pressure sensor at autozone for my truck then!?

I was thinking maybe I had a bad one. How does the EGR system on my truck work then?

 

It doesn't have one. Manufacturers use EGR when they need it to control NOx. If a company can meet the emission standards with cats, calibration, etc., then it won't have to pay for the initial expense and warranty coverage to support other components like EGR. Apparently, it was possible to certify the 4.0L to the 2003 standards without EGR.

 

ha ok, well once again bob you save the day, thanks again.
