Code P2135 2009 Nissan Altima Sedan Description

The P2135 diagnostic trouble code (DTC) in a 2009 Nissan Altima Sedan indicates an issue with the throttle position sensor (TPS) circuit, specifically related to its range or performance. 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 adjust the air-fuel mixture and control the engine's performance.
