Cm 870 oil temp gauge

[Craag]

Tried searching not finding anything really oil temp sensor related on the entire internet. Lots of oil pressure sensor video replacement guides..

My temp gauge (05 International 9900) is not working it's just flatlined. Now if this wasn't working or had a broken wire or the temp sensor was shot would this not throw a code or cause a shutdown?Or am I looking at a working sensor but the gauge or wiring isn't functional?

I know if my coolant gets too hot warnings come on the dash.

Finally is this sensor located beside oil pressure sensor behind the fuel filter area? I'm assuming it is as it's the hardest one to get at lol.

Thanks in advance![/align]
