I don't know how to diagnose sensors..... I think the speed control sensor may be out.
But the haynes manual doesn't specify if it affects my situation.
I have a dead speedometer, odometer, no cruise control, and no overdrive, (AT). I can't understand why all of these could have gone out at once, and I really don't want to have to pay Honda techs to figure it out. I have a check engine light when I slow to a stop, and no idea why.
Once I blew an ACG fuse, but after I replaced it, no more problems there.
Help......
