VSS - Vehicle Speed Sensor

[Neme]

On an AU3 XR8....

What do these do? I ask because my speedo works fine, but my ECU is throwing a code for the VSS......?

Will the VSS effect the engine/tune etc in any way if throwing a code?

Maybe not - the VSS is used as an input to the PCM and ABS systems as well as providing data to the cluster via CAN bus.

So what is the fault code ??

I use Forscan and it literally says VSS, not sure what the code number was.

Was throwing a cam posi sensor fault too which I replaced and it went away.

So I got under there today.

There was some oil seepage on the sensor, cleaned it all up then pulled the plug apart, wasn't easy as there was some green corrosion on the pins. Cleaned it all out and put it back together full of RP7 and the VSS fault code is gone...

Im getting this code on my s3 xr8 too,im assuming its the speedo sender that causes this?
Might have to give mine a clean too,my speedo also works fine.

Is it the only code you are getting? Are you getting other codes as well? Just wondering because if you are getting heaps of different codes at the same time, it may point to a earthing issue previously mentioned in another thread i linked for you, good luck sorting it mate.

I think I had the same issue with my AU Fairmont turned out to be a faulty ABS module
as Maka has mention what other codes are you getting ??
