July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Vehicle Speed Sensor (VSS)

  1. A/T -  The vehicle speed sensor is mounted on the transmission. The vehicle speed sensor generates a 16-pulse signal for every rotation of the front differential and sends it to the transmission control module (TCM). The signal sent to the TCM is converted there into a 4-pulse signal, and then sent to the ECM and the combination meter.
  2. M/T -  The vehicle speed sensor is mounted on the transmission. The vehicle speed sensor generates a 4-pulse signal for every rotation of the front differential and sends it to the ECM and the combination meter.
