Code P0122 2007 Nissan Maxima Description

The P0122 code for a 2007 Nissan Maxima 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 fuel management 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 fuel delivery and ignition timing for optimal engine performance.
