Question

WHILE DRIVING I HAVE SPEED O METER AND THEN IT RETURNS. SPEED SENSOR HAS BEEN REPLACED WITH A OEM PART AND TESTS GOOD. PROBLEM STILL PRESENT, ITS NOT ALL THE TIME AND WE ARE TRYING TO LOCATE POSSIBLE LOCATION OF PROBLEM

Answer 1

Here a possible location of the problem, right where the parking brake assembly is at, check for any wire or harness that may have made intermittent contact and inspect for any wiring chaff at that area which would lay along the parking brake mechanism
