Code P0112 2006 Scion xB Description

The P0112 diagnostic trouble code (DTC) for a 2006 Scion xB 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 and ignition timing to optimize engine performance and fuel efficiency.
