Stepper Motor (Throttle Actuator)
The stepper motor is the electromechanical actuator that controls the throttle plate position; failure prevents the controller from regulating the air-intake during the start sequence. This leads to 'Overcrank' (1102) or 'Underspeed' (1603) error codes because the engine cannot maintain the 3600 RPM required for 60Hz output. Replacing the motor restores the governed throttle loop and clears the start-sequence fault.
