I am having the same problem. It freed up and rotates freely now but what is causing the problem. I was getting a code 6 and changed the angle sensor and it seemed to fix it. about 3 hours of riding (at different times) later, I get a code 5 (control motor lock). After it is freed up, I still cant get it to work. Do you think it killed my angle sensor?When it jams and gives the "motor lock" code you can break it free with a screwdriver ... If it isn't jammed and just turns very hard the problem is with the Hondamatic..
