Code P0113 2004 Nissan Maxima Description

The P0113 code on a 2004 Nissan Maxima indicates a problem with the Intake Air Temperature (IAT) sensor circuit being too high. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal performance and efficiency. When the sensor detects a high voltage signal, it means that the temperature reading is higher than expected, which can lead to various issues in the vehicle's operation.
