Code P0072 2016 Chevrolet Silverado Description

The Engine Control Module (ECM) monitors the ambient air temperature sensor with a low reference circuit and signal circuit. The ECM monitors the voltage drop across the sensor, which is inversely proportional to temperature. When the ambient air temperature is cold, the resistance of the sensor is high. When the ambient air temperature is warm, the resistance of the sensors is low. The engine control module converts the voltage value to a temperature value and sends the value to the Display Module via serial data. The Display Module displays the temperature. The Diagnostic Trouble Code (DTC) will be set when the ECM detects the Ambient Air Temperature Sensor signal is more than 88°C (190°F).
