Code P2101 2007 Nissan Sentra Description

The P2101 diagnostic trouble code (DTC) for a 2007 Nissan Sentra relates to the Electric Throttle Control Performance. This code indicates that there is a malfunction in the electronic throttle control system, which is responsible for regulating the amount of air entering the engine. The throttle control module communicates with the engine control module (ECM) to adjust the throttle position based on driver input. When this system malfunctions, it can lead to poor engine performance, reduced fuel efficiency, and potential safety hazards.
