Decoding the BMW P0113 Code: A Comprehensive Guide
When your BMW’s check engine light illuminates and throws a P0113 code, it’s crucial to understand what’s happening under the hood. This diagnostic trouble code (DTC) indicates a potential issue with the Intake Air Temperature (IAT) sensor circuit, specifically suggesting a high input signal. Let’s delve into the intricacies of this code and explore how it affects your ultimate driving machine.
