Yeah if the speedo doesnt work its a wheel sensor - I forget which one but I think its right rear? Should be an easy R&R - you have to remove the wheel, caliper, and brake rotor to get to it I think - not too bad, an indy should have it done within an hour

Get the Genuine wheel sensor, not chinese aftermarket
