The sensor in my 92 was worn out, and bumps would make it go in and out. They have to be fairly tight to work. It only takes a couple min to swap.

 

how much does a new one cost?

TROUBLESHOOTING TIPS
If your speedometer and odometer both do not work it could be a problem in the car with the Vehicle Speed Sensor, called the VSS for short. This device sends pulses to the speedometer head (and cruise control) when the car is moving.

For cars with cruise control you can try a simple test. If your cruise control works it means the VSS is ok. Most likely it is the speedometer head, but could be the wiring from the VSS to the speedometer head. For absolute proof the car should be jacked up and the wheels turned while viewing the VSS input signal with a scope at the input connector to the speedometer, but nine times out of ten you have a bad speedometer. (On some cars a voltmeter will work. Just look for a fluctuating voltage on the VSS output when the wheels are turned.) If it is the speedometer head we would be glad to complete the repair for you, with a one year warranty. Just send the speedometer to us for repair. For a price quote email us at ecs@CarRadio.com

For cars without cruise you need to do the test with a scope as mentioned above. If you don't have a scope you can also send us the speedometer for a inexpensive bench test.

oh i forgot the best part is that the sensor was only 40.00 bucks and took less than 5 minutes to swap them out.
