DTC P2111 Throttle Actuator Control System - Stuck Open; DTC P2112 Throttle Actuator Control System - Stuck Closed: Description
WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The throttle actuator is operated by the ECM, and opens and closes the throttle valve using gears. The opening angle of the throttle valve is detected by the Throttle Position (TP) sensor, which is mounted on the throttle body. The TP sensor provides feedback to the ECM in order that it can control the throttle actuator, and therefore the throttle valve, appropriately in response to driver inputs.
HINT:
This ETCS (Electronic Throttle Control System) does not use a throttle cable.
