p0480 CEL but fan is working fine and actually over cooling

I have a 2012 Jeep Grand Cherokee. I'm getting P0480 CEL but my fan is working on over drive and overcooling my vehicle. I tried switching the relay in the TIPM(fuse box) and still getting the same code.

Answer this question I have this problem too

Is this a good question?

@darrylmercer45 you are dealing with a model that is plagued with a bad TIPM. This could be related to that. Something as simple as corrosion of the TIPM, corroded wires/connector as well as a failed TIPM could be causing this.

I was thinking the same thing but don't want to fork out the $$ for a new TIPM if a relay or thermostat could be a possible issue.
