Code P0113 2018 Chevrolet Silverado Description

The P0113 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado relates to the Intake Air Temperature (IAT) Circuit High Input. This code indicates that the signal from the IAT sensor is reading a temperature that is higher than expected by the Engine Control Module (ECM). The IAT sensor is a crucial component of the vehicle's engine management system, as it measures the temperature of the air entering the intake manifold. This information is used by the ECM to calculate the ideal air-fuel mixture for combustion in the engine. When the IAT sensor reports a high input, it can lead to a variety of performance issues in the vehicle.
