If you get two seperate codes, one relating to the speed sensor, cant remeber the exact numbers, then its the same problem I had. My car is and import version 5 1998, so the speed sensor/cable should be the same type. The thing I fitted then removed after it failed, was a smalled circuit board in heat shrink, with four wires, one wire dosent get used. generally found behind the dash or on the speed sensor cable coming out the gear box. Do your clocks show in Km then?
