Code P0112 2011 Nissan Rogue Description

The P0112 diagnostic trouble code (DTC) for a 2011 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 data is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. A low input signal suggests that the IAT sensor is reporting a temperature that is lower than expected, which can lead to various performance issues.
