• Under above condition, if a suitable screwdriver touching the
pick-up surface of the speed sensor is moved, the tester read-
ing voltage changes (0

V or 12
V~O
V). If the tester
reading voltage does not change, replace the speedometer
sensor with a new one.
NOTE:
The highest voltage reading in this test will be the same as that
