DTC P1122: Electric Throttle Control Performance Problem: Description

Electric throttle control actuator consists of throttle control motor and throttle position sensor. 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 throttle valve opening angle correct in response to driving conditions.
