Understanding DTC P0113
DTC P0113 in Chevrolet vehicles indicates a high input from the Intake Air Temperature (IAT) sensor. This crucial component measures incoming air temperature, allowing the Engine Control Module (ECM) to optimize fuel mixture and ignition timing. When the P0113 code appears, it suggests the IAT sensor is reporting abnormally high temperatures, potentially affecting engine performance and efficiency.
