2004 Dodge ram blanket heater sensor location

[SDozier]

I had my 2004 Dodge 2500 engine truble light come on and when I checked the code the tool told me that it was a battery blanket heater sensor. Where is the blanket heater sensor located? and what dose it take to replace it?

If your 04 is like my 05 the sensor is under one of the batteries. I forget which one.

The blankets aren't heaters, just insulative blankets. They moved the sensor during one of the early years of third gens. You may be able to follow the wire going under one of the batts.

on my truck its on passenger side underneath the battery box (under battery)
if you reach underneath u should feel it, its in the middle of the tray, and a few inches in from the turbo side

Ok thats good to know. Then our 03-04 are probably on the drivers side.

Do you know how to remove it and is there any testing for the unit or is it just a replacment thing.

Do you have the latest SW for your truck? I kinda remember a problem with battery temp codes, flashing check engine lights where new S/W was installed to stop it all.

Ok and Thanks, I will check with the Dodge delear and see if there has been a change, I was a bit suprized that a Bat. heater proplem would show up as a check eng. light.
