Code P2135 2009 Nissan Pathfinder Description

The P2135 diagnostic trouble code (DTC) in a 2009 Nissan Pathfinder indicates a problem with the Throttle Position Sensor (TPS) circuit, specifically related to its range or performance. The TPS is a crucial component of the electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). This data helps the ECM determine the appropriate fuel delivery and air intake for optimal engine performance.
