Code P2135 2008 Nissan Maxima Description

The P2135 diagnostic trouble code (DTC) for a 2008 Nissan Maxima indicates a problem with the Throttle Position Sensor (TPS) circuit. 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). The ECM uses this data to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
