Posted May 4, 20205 yr 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.
May 4, 20205 yr Author That’s the one i looked at any idea what size socket needed. It’s bigger then 1 1/16
May 4, 20205 yr I haven't checked mine but a quick internet search turned up a size of 21mm. Not sure how accurate that is though.
May 4, 20205 yr Author 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. It is a 13/16 deep socket works great Thanks for the pic.helped alot
May 4, 20205 yr Owner Check error codes. Voltage too high is typical for broken wires too. So if there is nothing plugged in it will show the highest reading.
May 4, 20205 yr Owner No Bus from the PCM... 23 minutes ago, Acetcruiser said: Only code I have is p1698. IAT sensor should throw a P0113 code because its was disconnected. You might be having ECM problems too.
May 5, 20205 yr Author I finally got back to the truck. (Been getting my boat ready for summer while I’m off work) unplugged the iat sensor today and ran the truck Got code p0113 plugged it back in cleared code and it didn’t come back but still reading 300 degrees all the time plugged in or not
