I have read the info on existing threads but it does not seem to apply to me. So hear goes While driving the gem flashed code 81 and acted like I slammed on the brakes This happened several times I limped home started reading existing threads. Went out this morning all is fine. Decided to check magnet there is a little black cover over the end of motor that I assume is the sensor after removal there is a bolt that holds what I guess is the round magnet in place all seems fine. It does not correspond with what I have been reading I presume it has changed on newer years any help and or ideas would be appreciated  
Thanks for your contributions Jack
