Code P0122 2012 Nissan Rogue Description

The P0122 code for a 2012 Nissan Rogue indicates a problem with the Throttle Position Sensor/Switch '1' Circuit, specifically a low input signal being detected. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic control system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). The ECM uses this data to determine the appropriate air-fuel mixture for combustion in the engine. When the TPS '1' circuit is reporting a low input, it means that the voltage signal from the sensor is lower than expected, which can lead to various performance issues.
