Where is it located on a 98.5 2500 Cummins?????


i read online it was a 13/16 either mine is different or I’m looking at the wrong sensor

the one I’m looking at is on the drivers side of the engine.


my edge insight reads a temp of 300 all the time.  

(Unless its cause of my no bus problem).  But everything else works as it should.

Well just went out again and with it being darker out the flash light worked better and i found it. 

Removed it edge insight still says 300 with it plugged in or unplugged.  And it looked clean too.

Only code I have is p1698.    



IAT sensor should throw a P0113 code because its was disconnected. You might be having ECM problems too.
