    on my 03 it is set up a little differently, but i believe it is a sensor for some of the injection system.

    Ok I bite...whats a MAP sensor??...and thanks for your reply.

    I just plowed all around my shop,with it disconnected from the battery...

    Could this be some kind of anti corrosion device??

    I need this truck to plow approx 50 lane ways in the morning...and all the mechanics AROUND HERE don't work on Sat.:hammerhead: ...anyway...all the advice is greatly appreciated

    If it's got heavy wire going to it, it's not a sensor. Could it be some kind of intake manifold heater?

    Your best bet on short notice would likely be to check out the Dodge version of Lawnsite, here:
    Dodge Forum

    You'll likely have to register a User ID and post the same question in the appropriate section, but that's where I get all the assistance I need for my '95 D-2500 (which is gas, unfortunately).

    Also my Haynes manual only covers me up to 2001, but I am thinking if you look under a section covering the valve cover, it might tell you what that part is called (but I'm guessing that big thing with DODGE written on it is a valve cover, idk).

    You could also try pulling diagnostic codes with it disconnected.

    Closest thing I show is an Air Temperature Sensor, but that's on 94-98 Cummins.
    From what I can tell, the MAP sensor is towards the back, where those 3 wire harnesses are.
    This is all under Chapter 6 of my Haynes manual: Emissions and engine control systems (if that helps).

    If it is the ATS, it's probably no big deal other than your mpg will suffer some.

    try turning the key on 3 times then leave it on. It should check for codes and display them on the odometer.
