The P0113 code in your Chevy Silverado signals an issue with the Intake Air Temperature (IAT) sensor circuit. This sensor plays a crucial role in engine management, measuring incoming air temperature to optimize fuel mixture and ignition timing. When it malfunctions, various performance problems can arise.
Common causes of the P0113 code include:
1. Faulty IAT sensor
2. Wiring issues (damaged, corroded, or loose)
