Anyone with an X1 or S3 that could possibly do me a favor? Unplug your speed sensor and with the key powered on..... could you test the white wire at the plug?

Do you get a voltage reading? of so, what?

Voltage on the grey wire should be 12v.

thanks

Not sure of your question. The white wire will be sensor output, so voltage at the harness plug would be ( wild guess on my part) 0v, as it runs straight to the speedo.

Would not be surprised if the speedo is reading a frequency on the white wire, not a voltage. Frequency based on transmission output shaft RPM.

Hope this helps. Don't know if I did. Dave

thanks for the reply. Im trying to get my new motogadget PRO speedo working with my factory VSS. Thanks to Revival they are getting me going in the right direction.
I now just need to get my GPS going to have the speedo teach itself.

Yes, it puts out spikes of voltage. Each time the sensor reads a gap in the spinning hunk of metal underneath it, there's a spike. It is a hall effect sensor. The speedo counts these pulses.

wired in a resistor between the power and white signal wire. I am now getting a speed reading after using the "teach function" but its still off as i was not traveling at 50 as the instructions say. Need to break out my gps.

I was using a speedo app on my phone but the wind snatched it right out of my clamp.
Spun around in time to see a gravel filled side dump run right over it!!
