Surfdougyfresh Posted January 25, 2007 Share Posted January 25, 2007 Hey gang...just dropped the fiance off at the hair dresser and headed to starbucks to waste some time with my laptop. The speedo on my 98 outback quit along with the odometer on the way. Tach is still working though. Did a search and it looks as though the VSS sensor might be the culprit. What does VSS stand for...variable speed sensor? Where is this located on the car? Don't have my Haynes manual with me...Thanks for any advice.

nvexplorer Posted January 25, 2007 Share Posted January 25, 2007 VSS stands for Vehicle Speed Sensor I do believe and its probably located on or near the transmission. I'm sure if you provide the year and model of the car that someone with more info will help you out. Quote Link to comment Share on other sites More sharing options...
dmanaenk Posted January 25, 2007 Share Posted January 25, 2007 Is the speedo digital or analog? Quote Link to comment Share on other sites More sharing options...
Manarius Posted January 25, 2007 Share Posted January 25, 2007 The VSS2 is gone on your car. Replace it and your CEL will go away and your Speedo will work again. The VSS2 is the sensor at the front of the transmission. Quote Link to comment Share on other sites More sharing options...
Skip Posted January 25, 2007 Share Posted January 25, 2007 Doug, the problem as noted is with the #2 speed sensor. This unit is spun by a gear in the front differenial. A complete summary can be seen in this post, it has pictures of where it is located and a description of it's operating system. VSS#2 details and problems The sensor may be bad, the wiring may be bad or, as is my case, the gear driving it could be bad. It is a Hall effect switch -> sends pluses to the ECU and TCU. The pulse rate varries with vehicle speed. - the car will drive without it as the brain boxes use VSS#1 as a back up. At the bottom of this page are other links to this problem. Hope this helps Quote Link to comment Share on other sites More sharing options...
