Code P2101 2010 Nissan Pathfinder Description

The P2101 diagnostic trouble code (DTC) on a 2010 Nissan Pathfinder indicates an issue with the electric throttle control system's performance. The electric throttle control system, also known as drive-by-wire, eliminates the need for a traditional mechanical throttle cable and instead uses electronic sensors and actuators to control the throttle opening. When the engine control module (ECM) detects that the actual throttle position does not match the desired throttle position, it triggers the P2101 code.
