DTC P2102 Throttle Actuator Control Motor Circuit Low; DTC P2103 Throttle Actuator Control Motor Circuit High: Description

WARNING: This page is about a different variant/trim than selected.

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 sensor, which is mounted on the throttle body. 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.

HINT:

This Electronic Throttle Control System (ETCS) does not use a throttle cable.
