Code P0112 2010 Nissan Versa Description

The P0112 code in a 2010 Nissan Versa indicates a problem with the Intake Air Temperature (IAT) Circuit, specifically that the input signal is lower than the expected range. The Intake Air Temperature sensor is responsible for monitoring the temperature of the air entering the engine. This data is crucial for the Engine Control Module (ECM) to adjust the air-fuel mixture to ensure optimal combustion and performance. When the ECM detects a low input signal from the IAT sensor, it can lead to a variety of performance issues.
