Code P2135 2010 Nissan Pathfinder Description

The P2135 diagnostic trouble code (DTC) in a 2010 Nissan Pathfinder specifically refers to the Throttle Position Sensor Circuit Range/Performance. This code indicates that the engine control module (ECM) has detected an inconsistency in the voltage signals being sent from the throttle position sensor (TPS) to the ECM. The TPS is a crucial component that monitors the position of the throttle valve and relays this information to the ECM to regulate fuel injection, ignition timing, and other engine functions. When the TPS circuit is not performing within the expected range, it can lead to issues with engine performance, fuel efficiency, and overall drivability.
