Speedo is Inop altogether and Odometer lights up but isn't changing. Engine code read: output speed sensor malfunction. Also just had trans service and pilot bearing replaced. Been doing a little research and so far here is what I have done: 1)Checked fuses with VOM, but the odometer has power so it is not a fuse. 2)Pulled and replaced VSS, the engine light cleared but the problem remained. 3)I have a Brothers Speed Calibrator and the car which I purchased used most likely had different gears installed, but the rear diff was replaced under warranty while under my possession. I guess my question is: Is the speed calibrator most likely the culprit, or could a wire have been pulled loose by the mechanic? Do i even need the speed calibrator since I have stock gears now anyways? Any advice would be appreciated!
