Order of inspection
P2100 Throttle Actuator Control Motor Circuit/Open High
The P2100 code means the electronic throttle motor circuit is open, so the motor gets no current when the computer commands it. It can put the engine in limp mode with limited power and a high or unstable idle. Check the connector, wiring and fuse before you replace the throttle body.
