Code P0113 2009 Nissan Sentra Description

The P0113 code for a 2009 Nissan Sentra refers to the Intake Air Temperature (IAT) Sensor Circuit High. This means that the engine control module (ECM) has detected a high voltage signal from the intake air temperature sensor, which is typically located in the air intake system. The IAT sensor plays a crucial role in determining the air temperature entering the engine, allowing the ECM to adjust the air-fuel mixture for optimal performance and fuel efficiency.
