SOURCE: Speedometer and tachometer not working

This is a tricky one. You have two sensors for your speedometer and tachometer, if one is malfunctioning then both will. Check and replace if necessary, good luck

Speedometer not working on 1998 cadillac concours

You are right in thinking of the speed sensor. You should also have a check engine light on if the sensor has failed.
The sensor is mounted in the side of the transmission and takes the place of the speedo cable.

Speedometer won't dealer says no sensor in transmission.i changed the sensor in the rear diff.that didn't help.

If it doesn"t have a speedo cable it has to have a speed sensor. It is usually located on the drivers side of the transmission bolted into the tail housing. Sometimes they have a cable going to the sensor but was changed to just the sensor. Have you called a parts house like auto zone, and asked if they have a listing for a vehicle speed sensor for your vehicle> You do not have to go to the dealer all the time.By the way most speed sensors are on the outside of the trans not on the inside.Usually a 11mm wrench will remove the bolt that holds the sensor in place. Remove the bolt pull the sensor out and replace with new.

1994 honda prelude vtec speedometer tach problem

Possible speed sensor. I know the speed sensors are a problem with hondas. A new speed sensor is about $200 and can be easily replaced. It bolts to the top of the transmission on the firewall side. Do NOT buy an e-bay one. They are only about $30 but are junk
