What happens when intake air temperature sensor goes bad?
A malfunctioning IAT sensor may cause your vehicle to take longer to start on cold mornings. The faulty IAT sensor tells the car’s computer that the air in the intake is a different temperature than it actually is and may cause the vehicle to not deliver the proper fuel mixture to the engine.
Can you clean intake air temperature sensor?
The air temperature sensor is a solid state component. If the sensor is dirty, you can clean it to make it work again. Use an electronic cleaner to clean the sensor after removing it from the intake manifolds.
What does the outside ambient air temperature sensor do?
It is the job of the ambient temperature sensor to measure the external temperature of the vehicle as a reference point for the computer to make calculations. The computer will continuously monitor the signal from the ambient temperature sensor and make automatic adjustments as needed to maintain cabin temperature.

What should the temp be on a Freightliner?
Temp would still read up in the 160* range and would work its way up to 200*, which would then set a fault in the ECM. Checked again with a different Freightliner in Grand Junction, CO, and they had to do a little bit of some digging to find the correct one.
