Code P0223 2006 Toyota Prius Description
The P0223 diagnostic trouble code for a 2006 Toyota Prius indicates a problem with the Throttle/Pedal Position Sensor/Switch 'B' Circuit High Input. This code is specific to the throttle position sensor (TPS) or pedal position sensor, which are crucial components in the vehicle's electronic throttle control system. The TPS is responsible for monitoring the position of the throttle valve and sending signals to the engine control module (ECM) to adjust fuel and air mixture for optimal performance. When the ECM detects a high input signal from the TPS or pedal position sensor, it triggers the P0223 code.
