Is there a difference between a VSS and an OSS sensor? I am getting a 452 code and the speedo is out along with the OD light flashing. This happened as I exited the FWY so the cruise was no longer set and the car seemed to shift ok. I had control of the OD button but the light still flashed.
Thanks

The sensor you need to look at is located on the transmission where the speedometer cable normally attaches. It is either the VSS sensor or the speedometer gear attached to the VSS sensor. The VSS feeds input to the speedometer and EEC. The VSS also provides an input to the cruise control module. The OSS sensor is also used in autos to directly measure transmission output shaft speed.
