Code P0112 2006 Nissan Sentra Description

The P0112 code for a 2006 Nissan Sentra indicates a problem with the Intake Air Temperature (IAT) sensor circuit, specifically a low input. 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 detects a low input from the IAT sensor, it may result in various performance issues due to incorrect fuel delivery and ignition timing.
