Code P2111 2010 Toyota Camry Description

The P2111 diagnostic trouble code (DTC) for a 2010 Toyota Camry indicates a problem with the Throttle Actuator Control System being stuck open. This system is responsible for controlling the throttle valve in the engine, regulating the amount of air that enters the engine for combustion. When the throttle actuator is stuck open, it means that the throttle valve is not closing properly, leading to an increase in the amount of air entering the engine. This can disrupt the air-fuel mixture ratio, affecting the engine's performance and efficiency.
