Hello Newb here

I have a 2006 6.0
Im getting a Low EGR flow code. I cleaned and then eventually changed the EGR valve. It seemed to work for about 1000 mles now the code is back, Ive cleaned it, reset the codes but no luck. Im not ready for an EGR delete yet but I dont see any sense in trying a new EGR valve. The only other thing Ive done to it was have the Fan clutch replaced about two months ago.... Any Ideas?

Thanks!

 

You may have an issue with your IAT2 sensor, MAF sensor, or the EGR cooler itself could be plugged up.

A little bit of intrusive diagnosis is required here.

Specifically, what is the code number that you're getting?

And the replacement valve, does it have a purple and a silver paint dot on the black plastic part on top?
