VSS Input Voltage Test

1. Use the multimeter and select VDC.
2. Turn ignition switch ON.
3. Measure voltage as per following table.
PIN A and PIN B = Battery Voltage
If voltage is not as specified. Test positive and
ground separately.

VSS Signal Test

1. Lift rear of vehicle so that rear wheels are off
the ground.
2. Set transmission to Neutral.
3. Turn ignition switch ON.
4. Set multimeter to VDC.
5. Measure voltage while slowly rotating rear
wheels by hand.
PIN B and PIN C = Alternate reading between
battery voltage and 0 VDC.
NOTE: Since we measure pulsating voltage,
the numeric display will continuously change.
The analog display may be easier to follow.
