WTH is a wheel sensor?Try hitting the Reset button on the bottom of the controller. I've never had that do anything glorious, but it also doesn't hurt to try. Clean the contacts where the Motherboard and the Flex board meet, just a Q-tip and some rubbing alcohol. Make sure that piece of foam is still in the frame there under the contacts of the Flex board, as it helps to keep pressure and make that connection between those when the controller is all together. Using a piece of paper under that foam strip to shim it just a shade can also sometimes help as that will put more pressure on the contacts. If none of that works, try a new Flex board.
