Code P2135 2007 Nissan Pathfinder Description

The P2135 diagnostic trouble code (DTC) for a 2007 Nissan Pathfinder refers to the Throttle Position Sensor Circuit Range/Performance. This code indicates that there is a malfunction in the throttle position sensor (TPS) circuit, which is responsible for monitoring the position of the throttle pedal and sending signals to the engine control module (ECM) to adjust the air-fuel mixture for optimal performance. The TPS is a crucial component in ensuring smooth acceleration, fuel efficiency, and overall engine performance.
