Code P2109 2013 Toyota RAV4 Description
The P2109 diagnostic trouble code for a 2013 Toyota RAV4 refers to an issue with the Throttle / Pedal Position Sensor 'A' Minimum Stop Performance. This means that the Engine Control Module (ECM) has detected that the throttle position sensor is not functioning correctly, specifically in terms of reaching the minimum stop position. The throttle position sensor is a crucial component that monitors the position of the throttle valve, which in turn controls the amount of air entering the engine. When the sensor fails to reach the minimum stop position, it can lead to various performance issues and potentially cause further damage if left unaddressed.
