Code P2135 2011 Nissan Pathfinder Description

The P2135 diagnostic trouble code (DTC) for a 2011 Nissan Pathfinder refers to the Throttle Position Sensor Circuit Range/Performance. This code indicates that the Engine Control Module (ECM) has detected a discrepancy between the actual throttle position and the expected throttle position. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve and sends this information to the ECM to adjust fuel delivery and ignition timing. When the ECM receives conflicting signals from the TPS, it can lead to drivability issues and potential safety concerns.
