Code P0123 2010 Nissan Rogue Description

The P0123 code for a 2010 Nissan Rogue indicates a problem with the Throttle Position Sensor/Switch '1' Circuit High Input. The throttle position sensor (TPS) is a crucial component of the engine management system, as it monitors the position of the throttle and sends this information to the engine control module (ECM). The ECM uses this data to determine the appropriate fuel injection and ignition timing for optimal engine performance.
