Code P0113 2007 Toyota Highlander Description

The P0113 diagnostic trouble code (DTC) for a 2007 Toyota Highlander indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high input. The IAT sensor is responsible for monitoring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to calculate the correct air-fuel mixture for combustion. When the ECM detects a high input from the IAT sensor circuit, it means that the temperature reading is higher than expected, potentially leading to incorrect fuel delivery and engine performance issues.
