Code P0110 2005 Scion xB Description

The P0110 code for a 2005 Scion xB indicates a malfunction in the Intake Air Temperature (IAT) 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 detects a malfunction in the IAT circuit, it can lead to various performance issues and potentially cause long-term damage if not addressed promptly.
