FIX!!! TYRE PRESSURE MAL ABS TRACTION CONTROL FIX

I had a tyre pressure malfunction warning on car as well as traction control and abs on dashboard, my park assist would disable and so would hill start. I tried everything changed speed sensor and hub on rear drivers side as instructed by mechanic even attempted new tpms sensor and spent 150 quid to Ford for them to tell me what I already knew. If your park assist isnt working along with having the messages pop up in your car it will be your speed sensor/abs sensor on the rear passengers side of vehicle as park assist only scans on the left side make sure you get a genuine part from ford's and that it's compatible with park assist. Hope this works for you if not you can try new hub/maybe a brake in the wire or worst case scenario abs faulty.
