[donsdisco]

ok...just got a 95 disco w/3.9L. drove this thing from MAINE to Tennessee with absolutely no problems. (!!!) the first weekend home, I was playing with the differential. on this rover the diff is stuck due to lack of use, however i can shift it into neutral. well, just doing that twice and the darn check engine light comes on. ok, i see that the code reads 68 ... speed sensor. everything runs fine -absolutely like a charm, so i'm still driving it around. however, when i have time, i want to check into this. every code description for this code says to "test 25 of continuty test procedure". well i have a service manual cd with the electrical diagnostics, and i can't find "test 25 of continuty test procedure". please help me find this crazy test so i can fix my baby!
