Code P0223 2005 Toyota Prius Description

The P0223 diagnostic trouble code (DTC) for a 2005 Toyota Prius indicates a problem with the Throttle/Pedal Position Sensor/Switch 'B' Circuit, specifically a high input signal. This sensor is responsible for monitoring the position of the throttle pedal and transmitting this information to the engine control module (ECM) to adjust the throttle accordingly. When the ECM detects a high input signal from the sensor, it means that the voltage being sent is above the expected range, indicating a potential issue with the sensor or its circuit.
