1992 Plymouth Voyager mileage: 100,000. My speedometer decides at times to not work at all- when this occurs, the odometer does not turn either. The auto shop found speedometer cable for me but I don't think that my 1992 even has a cable for this- Haynes repair manual does not help much- can’t find it - and there isn't any good drawings for showing where it is. How can I tell if it is a cable or a speed sensor or something else since it affects the odometer also? Tired of guessing how fast I'm going which is usually slower than anyone on the road to be safe than sorry and get a ticket.
You are correct, your van does not have a speedometer cable; it has a vehicle speed sensor generator that is located in the transmission. The vehicle speed sensor generates a signal for the speedometer.
