Code P0123 2009 Nissan Rogue Description

The P0123 diagnostic trouble code (DTC) in a 2009 Nissan Rogue indicates a problem with the Throttle Position Sensor/Switch '1' Circuit having a high input. The throttle position sensor (TPS) is a crucial component in the engine management system that monitors the position of the throttle blade. It sends this information to the engine control module (ECM) to adjust fuel delivery and ignition timing accordingly. A high input signal from the TPS can lead to incorrect fuel and air mixture, affecting engine performance and efficiency.
