2. INSPECT SPEEDOMETER ON-VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
USA (mph) CANADA (km/h)
Standard indication Allowable range Standard indication Allowable range
20 18 - 24 20 17 - 24
40 38 - 44 40 38 - 46
60 58 - 66 60 57.5 - 67
80 78 - 88 80 77 - 88

120 115 - 130
140 134 - 151.5
160 153 - 173
If error is excessive, replace the speedometer.

3. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1
and negative (-) lead to terminal 2.
3
(b) Connect the positive (+) lead from tester to terminal 3 and
1 the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0 V to 11
2
V or more between terminals 2 and 3.
N02332 HINT:
The voltage change should be 4 times for every revolution of
the speed sensor shaft.
If operation is not as specified, replace the sensor.
4. INSPECT FUEL RECEIVER GAUGE OPERATION
Fuel Receiver Gauge
Ignition (a) Disconnect the connector from the sender gauge.
Switch (b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.

Side Fuel
Sender
Battery
Gauge
I12367
Fuel Receiver Gauge (c) Connect terminals 2 and 3 on the wire harness side con-
Ignition Switch nector through a 3.4 W test bulb.
3.4 W
test (d) Turn the ignition switch ON, check that the bulb lights up
bulb and the receiver gauge needle moves towards the full
side.
Wire Harness
Battery Side
HINT:
1 2 3 Because of the silicon oil in the gauge, it will take a short time
4 5 for needle to stabilize.
I00844 If operation is not as specified, inspect the receiver gauge resis-
tance.
5. INSPECT FUEL SENDER GAUGE RESISTANCE
3 2 Measure the resistance between terminals 2 and 3 for each
float position.
