Speedometer

The Vehicle Speed Sensor (VSS) receives ignition voltage whenever the ignition switch is in the "ON" or "START" positions through the Audio Alarm Module and Junction Block 3. The VSS is permanently grounded through the Instrument Cluster to G202. When the drive wheels are rotating with the transaxle in gear, the VSS sends a square wave frequency signal to the Speedometer at the rate of approximately 2,000 pulses per mile. The Speedometer converts the frequency into a vehicle speed that is displayed on the Speedometer. The higher the frequency, the higher the vehicle speed, and the lower the frequency, the lower the vehicle speed.
