Code P0110 1998 Toyota Camry Description

The P0110 code for a 1998 Toyota Camry indicates an issue with the Intake Air Temperature (IAT) Circuit. The IAT sensor is responsible for measuring the temperature of the air entering the engine to help the Engine Control Module (ECM) adjust the air-fuel mixture for optimal combustion. When this circuit malfunctions, it can lead to incorrect readings being sent to the ECM, affecting the engine's performance and fuel efficiency.
