So I was driving along today in my civic, and all of a sudden the speedometer stopped working. It twitched around a bit and then settled on 0. Now, the car idles at about 1300 rpms and it runs rich all the time and the air/fuel ratio gauge doesn't bounce like in open loop any more at all. Anyone had this problem or have a solution, please respond. I'm going crazy with this car. Thanks!

Right.. I just need to know where the VSS is located at. I will check the fuses, too and see if anything is grounded out. Thanks for the info!!

 

If you look at your throttle body, then look straight down you will see a plug with three wires in it on the transmission, that is your Vehicle Speed Sensor (VSS) plug.

 

Thank you so much.. I'm off to check it out.. I'll report back
