The Egr is used to lower NOx. The 5.0 engines are equipped with the electronic exhaust gas recirculation system. This system relies upon the PCM for EGR control. The PCM calculates the desired flow of exhaust gases into the combustion chamber and subsequently contolrs the EGR valve position with the EGR vacuum regulator. The EGR valve postion sensor detects the exact position of the EGR valve pintle and relays the information to the PCM. The PCM in turn, uses this information to regulate the duty cycle of the EGR vacuum regulator ( solenoid on your fender).

hi, now i have another question does the car half to reach a certain temparture for the the egr to work and if so how hot does it half to be before the egr has to open because when i let the car get warmed up i take the vacum line off the egr valve and give it gas to see if i am getting any sucksion i not getting any

I am pretty sure that there is no temp the Egr starts to work at. But I do know that you have to be driving for the Egr to start to open. And If I remember correctly I do not get any vacuum on my line on my car either. But a good way to make sure you have vacuum is to pull the other line off of the solenoid that goes to the intake and check for vacuum.

hello, again ok i do have vacum from the pelium to the solenoid on the fender well, now another question for u on the back of my pulltion pump i have a valve that is called a air management valve that has a vacum line that runs off of [AMV] is this post to be sucking air if so i dont feel any suckison from it the ( valve) now the vacum line that comes off the air management goes to the side of the fender well also, to what looks like a relay switch to me, so my question is the air management vavle post to suck air.
