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 |

...sounds about right....frequency pulse width pattern converted to register in speedo in mph....LT |

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. |

If its hall effect it is not compatible |

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!! |
