Where's the 2nd VSS located
 

My check engine light is on and gave me the code for a bad VSS. I replaced it, the light stayed off for a day or 2 then came on again. The OD light blinks when the car is first started and when testing the tranny, gives me the same code. The speedo is working fine, so what I am thinking is that the second VSS is the problem. Where the heck is it located though?

There's only one vehicle speed sensor.

You have two in the front of your head (for seeing how fast the scenery goes past)

You car only has one, though.
