I am having the strangest issue with my ms. The coolant temperature will display at 120f with the ait plugged in, but as soon as I unplug my ait it will go to the correct value of 67f. Anyone ever experienced this and have a solution for it?

 

There is a fall back value of around 67 degrees in there for when it detects an unplugged sensor. What MS variant is this?

 

Ms1 v3.0. Not sure what's going on. I do have continuity to the sensor from the signal wire on the computer. Tried changed out sensors but no dice. Possibly the circuit for the coolant sensor is acting up and I need to remake it.

 

Make sure you have the proper INC files for your sensor copied into your TunerStudio project's INC folder.
