Code P0113 2012 Nissan Altima Sedan Description

The P0113 diagnostic trouble code for a 2012 Nissan Altima Sedan indicates a problem with the Intake Air Temperature (IAT) sensor circuit being too high. The IAT sensor is responsible for monitoring the temperature of the air entering the engine. This information is crucial for the engine control unit (ECU) to adjust the air-fuel mixture to optimize combustion efficiency. When the sensor detects a high voltage signal, it means that the intake air temperature is higher than expected, which can lead to a variety of performance issues.
