Temp and pressure are 2 different things.

Just for reference, a lot of the trucks I have look at, have that OEM ambient Temp Sensor disabled.

Also, a sensor would not say "disabled" unless it has been set that way, has nothing to do with a senors failing. Features and Parameters are options for the truck, not status displays.
