the sensors on the lift motor and on the heat sink are interchangable with drive motor sensor, swap them and see if the code changes, I have replaced lots of temp sensors. also check the 2 wires that follow the motor cables, pull hard on them, the wires will break inside and the outer cover will allow it to go open intermittanly
Oh, I reread your post, you said intermittantly. Perhaps the motor is just overheating??

No such thing as a 66, probably a 6G. Lift motor temp sensor out of range. You can run test A09 if you have the superword, however you probably have a failed sensor. Disconnect it from the system card at JPS6, resistance across it should be about 2000ohms at room temp, rising a little if you GENTLY warm it. I bet a wire is broken off at the motor....
