This is because of hall sensor abnormal, and most time is because hall sensor wires connection doesn't contact well, please kindly check the 5-wire hall sensor connector and also inside whether any pin bent doesn't contact well.If use quick release wire, please kindly check whether connector plugged very tight. If every connection is ok, then the most possible reason is hall sensor burned.
(Very important: during installation, if need to remove the white hall sensor plug, please don't let hall sensor connector terminal touch phase connector terminal, otherwise hall sensor is very easy to be burned)
