Code P0113 GMC Description

The P0113 GMC code indicates that the Intake Air Temperature (IAT) sensor circuit is registering a high input. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module to adjust fuel mixture and ignition timing, optimizing performance and fuel efficiency. A high input reading from the IAT sensor can lead to incorrect calculations by the engine control module, resulting in poor engine performance, decreased fuel efficiency, and potential drivability issues.
