Code P2135 2006 Nissan Pathfinder Description

The P2135 diagnostic trouble code (DTC) for a 2006 Nissan Pathfinder indicates a problem with the Throttle Position Sensor (TPS) circuit. The TPS is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending signals to the engine control module (ECM) to adjust the throttle opening accordingly. When the ECM detects that the TPS circuit's voltage readings are outside the expected range or performance parameters, it triggers the P2135 code.
