IAT "stuck"

[ShadowFromHell]

Ive been using my OTC 2000 to monitor my coolant temp reading the CTS. In doing this I've noticed my IAT is always reading 85 degrees. Doesnt matter if I am parked or going down the freeway. This cant be correct. So what would cause this? Bad sensor or wiring issue? I know it worked at one time because when I installed the FMIC I used it to see how much it helped. Also, what kind of issues would this cause?

Thanks

To see if its a sensor issue I would verify voltages at the plug and at the engine controller. If there is a difference its likely a wiring issue. If they are the same it would lead me to assume the sensor has gone bad.

I was wondering if 85 is a default setting. I dont think there is a code for the IAT if it goes bad.
