So does anyone know what sensor the ecu uses to determine the vehicles speed. Looking at the diagram at first I though it was the ABS wheel speed sensors but that doesn't appear to be the case. Currently I think I have whatever sensor it is unplugged and the tach now cuts out the second I go above 2500rpm. Any help would be awesome.
So the spedo is fixed but I'm really stumped on the tach issue. :sad:
Basically anything over 3100rpms and the the gage drops to 0. Under 3100 it reads accurate after that nothing when i speed up it stays at zero and then when i slow down where the rpm comes back into that range it starts working again. If I'm understanding it correctly it has to be the ECU or the cluster, any help would be greatly appreciated.
Possibly, not generally known, is that beyond the factory 3 year, 36,000 mile warranty, is the "Emissions" warranty.
If you are fortunate enough to have your car registered in either California, New Jersey, Connecticut, Oregon, Washington, Rhode Island, New York, Maine, Massachusetts, Pennsylvania, New Mexico, Florida or Colorado, there is a CARB, 7 year/70,000mile warranty on amongst other things the Instrument Pack.
