Thermo-couples are commonly used as temperature sensors. It measures and controls the temperature such as in the case of Engine Coolant Temperature. Besides, RTDs or Resistance Temperature Detectors also measure the temperature.
Why are oxygen sensors important to the engine?
They are responsible for monitoring the air fuel mixture of the engine, and their readings affect important engine functions such as timing and air fuel mixture. Over time, with normal use, oxygen sensors can begin to function with a delayed response, and they will eventually fail.
What should the temperature be on the IAT sensor?
Turn on the engine. Check the live data and check the temperature of the IAT sensor. Typically, the temperature readings should be 10 degrees more or less than the vehicle’s ambient temperature, depending on the outside temperature and the temperature of the engine.
