Have 2012 3500 Longhorn about 97,000 miles and deleted.

I'm using an MM3 tuner.

My fan clutch is pretty much matching my rpm's while driving around town.

Fan clutch was replaced about 2 years ago.

My thought process and troubleshooting tell me that the PCM is seeing a high temp somewhere and is commanding more fan speed. Now hold that thought.

In the MM3, I found a PID called "Intercooler outlet temp" The reading I'm getting is around 180-230F degrees.

Upon researching, it seems to be the MAP sensor. I unplug it, and the reading pegs at 392F, and when I reconnect it, it goes back down to 180-230F.

It's cold here today, and before starting the motor with just the key on and sensor removed and still connected, I was reading 151F, and it is 50F outside.

Here is my question: Does this sensor heat up to read air pressure like a MAF sensor?

Or should it read the actual temps going through the intake plenum?
