Code P0123 2008 Nissan Rogue Description

The P0123 code in a 2008 Nissan Rogue indicates that there is a high input signal detected in the throttle position sensor or switch circuit '1'. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve and sends this information to the engine control module (ECM) to adjust fuel delivery and ignition timing. A high input signal suggests that the voltage in the TPS circuit is higher than the specified range, which can lead to incorrect fuel and air mixture, affecting the engine's performance.
