Code P0111 2016 Chevrolet Silverado Description

The P0111 code for a 2016 Chevrolet Silverado indicates an issue with the Intake Air Temperature (IAT) sensor circuit, specifically a range/performance problem. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion and performance. When the ECM detects that the IAT sensor's signal is out of the expected range or not performing within specified parameters, it triggers the P0111 code.
