The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor 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 check engine light code.

Intake air temperature sensor circuit. It is located between the air filter and engine. Small 2 wire plug. These rarely go bad. Usually it is a wire broke. And they usually break right at the plug.
