Trouble Diagnoses

INSPECTION/VEHICLE SPEED SENSOR

CHECK VEHICLE SPEED SENSOR
OUTPUT.
1) Remove vehicle speed sensor from

transmission.

2) Check voltage between combination

meter terminals

q

21

and

q

28

while

quickly turning speed sensor pinion.

OK

E

NG

Vehicle speed sensor is
OK.

CHECK POWER SOURCE.

I

Re-install vehicle speed sensor.

I

Turn ignition switch to “ON” position.

Check voltage between vehicle speed
sensor connector terminal

q

1

and ground.

Battery voltage should exist.

OK

E

NG

Check harness for open or
short between speedom-
eter and vehicle speed
sensor.

CHECK GROUND CIRCUIT OF
VEHICLE SPEED SENSOR

I

Turn ignition switch to the “LOCK” posi-
tion.

Disconnect vehicle speed sensor connec-
tor.
Check continuity between vehicle speed
sensor harness connector terminal

q

3

and

body ground.
Continuity should exist.

OK

E

NG

Repair harness or connec-
tor
