Code P0113 2004 Infiniti G35 Description

The P0113 code for a 2004 Infiniti G35 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. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the IAT sensor circuit reports a high voltage, it means that the ECM is receiving a signal indicating that the intake air temperature is higher than it actually is. This can lead to incorrect fuel delivery, timing adjustments, and other engine functions, resulting in poor performance, decreased fuel efficiency, and increased emissions.
