I have a 1999 Subaru Legacy Outback w/60k miles. The speedometer stops working periodically along with the odometer. My 1990 Honda Accord did the same thing and I replaced a speed sensor on it to fix it. I dont know if the same thing is wrong with my Subaru.

I looked to see if I could find a part on the Subaru that looked like the one I replaced on the Honda but no luck.

Could you point me in the right direction?

Thank you very much,

Jason

I have the same problem with my 99 Outback. I am told it may be in the wiring harness that attaches to the transmission. A pricey item to replace on the hope that it is the problem, that's why I haven't done it yet. I am also told it is unique to the 99's.

the sensor is located on the front right side of the transmission. there is a 2-wire plug going into it. You will need a 10mm wrench to remove the clip that holds it in place, and to install the new one just drop it into place.
This happened to my legacy at ~62,000 also.

I am having the same intermittent speedometer problem in my 99 Legacy Outback. The dealer cannot find the problem. Any more information about whether its the sensor or a wiring harness or some other failure?
