Speedometer Intermittent / Dead

Hi Folks,

My 1992 Cherokee (4.0L Straight 6, Automatic) has been having speedometer problems. My wife drives it and reported that it was going to 0, then working again. then back to 0.

I poked around with the Vehicle Speed Sensor, took it out and tested it. The "test" was to connect an ohm-meter to the leads and spin the end with my fingers. It appears to be a switch that opens and closes with the speed of the car.

Anyway, it seemed to work when I tested it. I put it back in and the speedometer worked for about 1 minute, then went to 0, then worked for a few seconds, then to 0 again (where it is now).

Question: Has anyone else experienced this? Was it the sensor "dying" before it went dead, or was it something else?

Thanks for any input.

Take Care,

UPDATE:

Got a replacement Vehicle Speed Sensor (VSS) from AutoZone this afternoon & installed it this evening. About $48 + tax.

A quick test drive shows that the speedometer (and odometer) are working again. Looks pretty solid. So I think it is fixed.

I'm sure I will hear about it if it goes out again :smile:

Take Care,

you know it.
