All a IAT sensor is, is a thernistor that changes resistance based on temp. Though your engine will run “okay” it will not run as well as it should, without the IAT Sensor. The ECU simply cannot process all needed information properly.
What should IAT sensor read at idle?
Typically, the temperature readings should be 10 degrees more or less than the vehicle’s ambient temperature, depending on the outside temperature and the engine’s temperature. If the readings are not realistic, there could be a problem with your IAT sensor or the wirings to it.
How much does it cost to replace an intake sensor?
