Code P2135 2008 Nissan Sentra Description

The P2135 diagnostic trouble code (DTC) for a 2008 Nissan Sentra refers to the Throttle Position Sensor Circuit Range/Performance. This code indicates that there is a problem with the throttle position sensor (TPS) circuit, specifically related to the voltage signals it is sending to the engine control module (ECM). The TPS is a crucial component in the vehicle's fuel management system, as it helps the ECM determine the appropriate air-fuel mixture for combustion. When the TPS circuit is not functioning within the expected range, it can lead to issues with engine performance, fuel efficiency, and overall drivability.
