VEHICLE SPEED SENSOR (INSTALLED
ON
THE TRANSMISSION)
Fig. 8-371
The vehicle speed sensor is installed on the rear
portion of the transmission. (Fig. 8-371)
The number of pulses generated is four pulses per
one rotation
of the pinion shaft.

Battery
Fig. 8-372
1. Connect the vehicle speed sensor connector 1
IM-101 to the battery (+)terminal and 2 IM-101 to
the (-)terminal.
2. Connect a resistance of 1.3k ohm to Sk ohm ( 1/4W
or more) between connectors 1 ~ and 3
IM-101.
W CAUTION: Be extremely careful not to con­
nect the battery(+)
terminal to the
connector
3IM-1ol.
This may damage the vehicle
speed sensor.
3. Rotate the shaft of the vehicle speed sensor
1~1 slowly and measure the voltage at both ends
with a digital tester.
The voltage,
with one rotation of shaft,
fluctuates
four times in the following range
:10 to 14V <-> 2Vor less.
Replace the sensor when the resu It of i nspec­
tion is found abnormal.
