Code P2111 Toyota Description

The throttle actuator is operated by the Engine Control Module (ECM) and opens and closes the throttle valve using gears. The opening angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle with motor body assembly. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to driver inputs.
The ECM determines that there is a malfunction in the Electronic Throttle Control System (ETCS) when the throttle valve remains at a fixed angle despite a high drive current from the ECM. The ECM illuminates the MIL and stores a Diagnostic Trouble Code (DTC).
