Code P2135 2006 Infiniti G35 Description

The P2135 diagnostic trouble code (DTC) in a 2006 Infiniti G35 indicates a problem with the Throttle Position Sensor (TPS) circuit, specifically relating to range/performance issues. The TPS is a crucial component of the engine management system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). This data is used to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
