Code P2101 2012 Nissan Altima Sedan Description

The P2101 diagnostic trouble code (DTC) in a 2012 Nissan Altima Sedan indicates an issue with the electric throttle control system's performance. The electric throttle control system, also known as electronic throttle control (ETC) or drive-by-wire, replaces the traditional mechanical throttle linkage with an electronic system that controls the throttle opening. This code is triggered when the Engine Control Module (ECM) detects that the actual throttle position does not match the desired position set by the ECM.
