Code P0113 2005 Nissan Altima Sedan Description

The P0113 diagnostic trouble code (DTC) for a 2005 Nissan Altima Sedan indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high voltage. 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 for optimal combustion and performance. When the IAT sensor circuit reports a high voltage, it means that the ECU is receiving a signal indicating that the intake air temperature is higher than expected.
