its_masters Posted August 25, 2014 Share Posted August 25, 2014 My Speedo, odometer, and gas gauge went out in my 98 legacy outback. My tach and temp gauge still works. What could be my problem? Quote Link to comment Share on other sites More sharing options...

Caboobaroo Posted August 25, 2014 Share Posted August 25, 2014 More then likely is the vehicle speed sensor in the transmission that is going wonky. My '99 GT has a speedo head that will flake out every once and awhile but it's a speed head issue. Easiest way to find out if it's the sensor or the head, see if you can plug into the car with an OBD scanner and see if the ECU is seeing vehicle movement. If it reads 0mph while moving, it's going to be the sensor. If it reads the vehicle speed, it's going to be the speedo head. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted August 26, 2014 Share Posted August 26, 2014 If the speed sensor is bad youll have CEL codes for VSS and the trans may shift funny (if Automatic). Some of the 98-99 models had problems with the speedo head so that's a good possibility. Quote Link to comment Share on other sites More sharing options...
