How does the IAT sensor help the PCM?

With the IAT sensor, it get’s to know the temperature of that incoming air and then is able to better calculate how dense that air is. Calculating the flow rate and density of the air that the engine is breathing at any given time helps the PCM maximize everything from fuel consumption to performance.

How does the IAT work on a Nissan?

The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 Nissan check engine light code.

Can a bad IAT sensor cause fuel economy problems?

The IAT sensor then varies its internal resistance according to air temperature and sends a return signal back to the PCM.
