Code P2123 2006 Infiniti G35 Description

The P2123 code on a 2006 Infiniti G35 indicates a problem with the Accelerator Pedal Position Sensor Circuit Range/Performance. This sensor is responsible for sending signals to the engine control module (ECM) regarding the position of the accelerator pedal. The ECM uses this information to adjust fuel delivery and ignition timing to optimize engine performance. When the sensor circuit's range or performance is outside of the expected parameters, it can lead to issues with vehicle performance and drivability.
