2014 Engine Fan Runs Constantly
My fan never shuts off until I turn engine off. It runs as soon as I start it. Engine is not overheating but it seems odd that fan runs before engine is up to temperature??

Changed thermostat months ago because of running only 175 ish down road. It runs now 205-219 on the analog gauge.
Still need to change sensor? I looked on Rock Auto and they show all as sensors and only one as sender. The sender pic looked just like the sensor pic. So I assume there is only the sensor and not both?
Do you mean MAF sensor instead of MAS?

Reason I stated MAF could possibly be and issue was, just last week picking car up from dealership bodyshop and fan would not shut off ran for three days straight killed battery after service department looked at it, was diagnosed with bad MAF and of course dead battery.

Please post up the end result. I too have a 2014 and while I do not have any issues, I would like to build a reference folder for potential problems and solutions.

When I got the car it had a KN air filter in it. I promptly changed it for a stock air cleaner. Wondering if it sucked some oil from an over oiled KN onto the MAF sensor.
Think I will put some cleaner on it and see if that works. If not I will replace MAF as my CTS is working correctly. Gone for the weekend but will do this Monday after work and post results. Thank you all!

A dirty MAF sensor will not cause your fan to run…you would need a scan tool to look at your IAT, ECT, and AC Pressure data PIDS.
