VEHICLE SPEED SENSOR INSPECTION
INSPECT SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1 and
negative (±) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
negative (±) lead to terminal 2.
(c) Rotate shaft.
(d) Check that there is voltage change from approx. 0 V to 11 V
or more between terminals 2 and 3.
HINT: The voltage change should be 4 times for every revolu-
tion of the speed sensor shaft.
If operation is not as specified, replace the sensor. BE±46
