Hi there,If you have scan tool access, does the right front wheel produce a road speed now?If you can clear the previous C0040, and drive the vehicle to see if all wheels read road speed.Some cars need to be driven on the road after a repair like that, so the system sees all wheels rotating.Does not work on a hoist.Please let me know if you need any further assistance.Gary
