Code P0113 2004 Nissan Sentra Description

The P0113 code for a 2004 Nissan Sentra indicates a problem with the Intake Air Temperature (IAT) Sensor circuit registering a high voltage. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the engine control unit to determine the correct air-fuel mixture for combustion. When the sensor detects a high voltage, it means that the temperature reading is higher than expected, potentially leading to incorrect fuel delivery and engine performance issues.
