Code P0123 2006 Toyota Camry Description

The P0123 diagnostic trouble code (DTC) for a 2006 Toyota Camry indicates a problem with the Throttle Position Sensor/Switch 'A' Circuit High Input. This means that the engine control module (ECM) has detected a higher than expected voltage signal from the throttle position sensor (TPS) or throttle position switch. The TPS is a crucial component that monitors the position of the throttle valve in the engine, allowing the ECM to adjust the air-fuel mixture for optimal performance. When the TPS signal is too high, it can lead to incorrect fuel delivery and potentially affect the vehicle's drivability and overall performance.
