Code P2135 2011 Nissan Altima Sedan Description

The P2135 diagnostic trouble code (DTC) in a 2011 Nissan Altima Sedan 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 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). This data is used by the ECM to determine the appropriate air-fuel mixture for combustion, as well as the engine's operating parameters.
