Sometimes when the sensor or the cable is broken you can have this problem.
Did you tried a other motor?
I don't know whether it is sensored or sensorless. This is my first and only hobby grade RC car so I'm still a bit new to this. It is a clone of an Associated RC18 if that helps. My gut tells me that whichever one of those motor types is less expensive is what this one is.
I don't have another motor to try. If I had any spare ESC's, Radios, or motors then I'd try them to isolate the issue.
