Code P0122 2011 Nissan Rogue Description

The P0122 diagnostic trouble code (DTC) for a 2011 Nissan Rogue indicates a problem with the Throttle Position Sensor/Switch '1' Circuit, specifically a low input signal. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic fuel injection system, responsible for monitoring the position of the throttle valve and sending this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing, ensuring optimal engine performance and efficiency.
