DTC P2100-18: Throttle Actuator "A" Control Motor Circuit Current Below Threshold; DTC P2100-19: Throttle Actuator "A" Control Motor Circuit Current Above Threshold [12/2019 - 10/2022]: Description

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 with motor 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.

HINT:

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