What are the symptoms of a bad temperature sensor?
Symptoms of a Bad or Failing Evaporator Temperature Sensor (Switch) 1 No cold air from the AC system. 2 AC temperature fluctuates. 3 AC compressor does not activate.
When to replace the air inlet temperature sensor?
It should match the air inlet temperature (IAT) reading when the engine is cold, and gradually increase as the engine warms up. The sensor’s resistance also can be checked with an ohmmeter and compared to specifications for various temperatures. If the sensor is not reading correctly, it needs to be replaced.
How to diagnose the problem of engine hesitation?
How To Diagnose Problem Of Engine Hesitation. To diagnose the problem need a scan tool too checking the engine computer for misfire codes and any other fault codes. By looking at the various sensor PIDS (the scan tool will display sensor values) using a scan tool to checking a sensor response.

What are the symptoms of a bad intake air temperature sensor?
A bad intake air temperature (IAT) sensor may cause one or more of the following symptoms: stumbling during acceleration; difficulty starting; rich or lean air-fuel ratio; lean misfire, usually in a cold engine; rough idling when engine is cold; surging when engine is warm; increased fuel consumption; engine stalling or surging
How to fix a bad intake air temperature ( IAT )?
If this does not happen, it means that the internal computer is to blame, and that it is not producing the voltage that the IAT sensor needs to function. To fix a faulty intake air temperature sensor, remove all carbon and oil accumulation. If this does not fix the problem, replacing the unit is the best option. Like it? Share it!
What should the temperature be on the IAT sensor?
After turning it on, check for the temperature of the IAT sensor. It should be 10°F above or below the ambient temperature of the vehicle. If this is not the case, you may have a problem with the sensor.
Can a faulty air temperature sensor cause idle hiccups?
Idle is also one of these conditions when the engine is susceptible to the right air-fuel mixture. This is also a condition when you can feel the faulty air intake temperature sensor’s slightly faulty air-fuel mixture. If you experience some small hiccups on idle, it can be a faulty IAT sensor.
