WARNING: This page is about a different car, the 2002 GMC Sonoma and 2002 Chevrolet S10 Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The Transmission Scan Tool Data Definitions contain a brief description of manual transmission related parameters available on the scan tool. The list is in alphabetical order.
Vehicle Speed Sensor: Range 0-255 km/h (0-255 mph). The vehicle speed sensor signal is converted into km/h (mph) for display. The vehicle speed output from the PCM is 4,000 pulses per mile. The scan tool uses the Class 2 serial data from the PCM to obtain vehicle speed, while the instrument panel cluster, cruise control module and multi-function alarm module use the 4,000 ppm output.
