The diagnostic trouble code (DTC) P0113 is related to the Intake Air Temperature (IAT) Sensor Circuit High Input. When this code is triggered, it means that the IAT sensor is reporting a high voltage or temperature input that is higher than the specified range set by the vehicle's manufacturer. As mentioned before, the Intake Air Temperature (IAT) sensor measures the temperature of the incoming air into the engine's intake manifold. This information is used by the engine control module (ECM) or powertrain control module (PCM) to adjust the air-fuel mixture and ignition timing, optimizing engine performance based on the air density and temperature. Potential causes of the P0113 code include: 1. Faulty IAT Sensor: The IAT sensor may be malfunctioning, providing incorrect high voltage readings or sending a constant high temperature signal. 2. Wiring or Connector Issues: Problems with the sensor's wiring or connector can lead to a short to power or a high voltage sign...
