    Hi guys, I know this thread has been discussed before, just curious though Truck runs fine. I get a SPN 4752 FMI 7 code. happend after it was Windy. I wanted to know, does this usually mean Delta P sensor / Venturi Pipe or does it mean EGR cooler.. i am having difficulty understanding. Thanks

    its interesting, it happens on uphills I guess, thats what triggers it.. Nothing seems funky but I'm hauling a load for another 700 miles til I get home so lets see if anything changes. I read places that its the Delta P, but the book said it had to do with EGR Cooler. Not sure..

    Usuallyt egr Cooler gets plugged up and there is not enough egr flow and it throws a code common pratice is to remove egr cooler and clean it if you have some miles on your truck i would suggest replacing it all together because you are going to save yourself the labor.

    I
    I run Out of California, usually 300-400 miles a day.. Do you think I should have it cleaned? Truck has 580,000 miles , 2012. Also, is it related to the Delta P Sensor?

    if you have never replaced it i would say replace it labor is the same but the one you have on if original very unlikely it's going to make it another 100K without leaking inside this way you will just save the labor the second time around. and make sure they check the venturi tube in the delta p they like t plug up the holes

    Also wondering, do you think this can relate to any injector issues?

    Check the sensor, mine just coded the same today in Amarillo and this time it was just the sensor and an update for the programming.
