Code P0223 2007 Toyota Prius Description

The P0223 diagnostic trouble code (DTC) for a 2007 Toyota Prius indicates a problem with the Throttle/Pedal Position Sensor/Switch 'B' Circuit having a high input. This sensor is crucial for the proper functioning of the electronic throttle control system in the vehicle. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate air-fuel mixture for combustion in the engine.
