Here is an explanation of the trouble code.
DTC P2101 ELECTRIC THROTTLE CONTROL FUNCTION
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feedback to the ECM to control the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
ON BOARD DIAGNOSIS LOGIC
This self-diagnosis has the one trip detection logic.
Electric throttle control function does not operate performance
Harness or connectors (Throttle control motor circuit is open or shorted)
Electric throttle control actuator
When the malfunction is detected, ECM enters fail-safe mode and the MIL lights up.
Engine operating condition in fail-safe mode ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring.
