Code P0112 2009 Nissan Rogue Description

The P0112 diagnostic trouble code (DTC) for a 2009 Nissan Rogue indicates that there is a low input signal from the Intake Air Temperature (IAT) sensor circuit. 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 ECM receives a low input signal from the IAT sensor, it may not be able to accurately adjust the fuel mixture, leading to potential performance issues.
