I drive a 90' accord LX ATX. My speedometer/odometer aren't functioning, the sport light on the dashboard is flashing, the CEL has come on a few times. I searched and found a thread that identified these problems as the VSS, and that its code 17. unfortunatley i haven't found the service harness to pull the codes, but i found a VSS at the junkyard and replaced it anyways to see if it would work, NO CHANGE. anyways should i buy a brand new part, is there a way to tell if the old part is bad, and is there anyother place in the circuit/VSS that could be faulty? or could something else intirely be causing this?
