Code P2135 2012 Nissan Pathfinder Description

The diagnostic trouble code P2135 on a 2012 Nissan Pathfinder indicates a problem with the Throttle Position Sensor (TPS) circuit. The TPS is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate fuel delivery and throttle response for optimal engine performance.
