I recently brought a 05 scion xa with around 60k miles. First thing i noticed was that the check engine light was on and that the speedometer didnt work. The gauge of the gas is working fine so is the rpms, its only the mph that isn't working. So i changed the cluster and still the same problem. I plugged in the scan tool and i got back a few codes having to do with the vehicle speed sensor all 4 of them. C0200 and a few other codes. please help the speed senors are expensive and i want to know if its really that.
