. . . . I should add that all the work I did by myself. however the car was checked by two mechanics and twice by the dealership. They didn't tell me anything that I woulnd't know already.... :( . . . .
I would suggest checking each 5 volt reference circuit that powers a sensor. Check the sensor power feed for short circuits. This will be a tedious process and keep in mind that disturbing any wiring harness can make the short circuit / wire rub through disappear. Note that sensor power feed circuits have wiring splices which can cause problems. See attached image for example.
