    Fan clutch / MAP sensor questions

    Have 2012 3500 Longhorn about 97,000 miles and deleted. I'm using 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 is telling me that the PCM is seeing a high temp somewhere...
