Speed Sensor Test
- Disconnect wire harness connector at speed sensor. Connect a voltmeter set on low AC scale to wire terminals from speed sensor.
- Raise front and rear wheels of vehicle off ground and support vehicle with safety stands. Operate engine (wheels spinning freely) at 30 mph and note voltage.
- Voltage should be approximately 0.9 volts. Increases of 0.1 volts per each 10 mph increase in speed should also be noticed. Turn off engine and stop wheels. Lower vehicle. Connect speed sensor wire harness.
