5. INSPECT VEHICLE SPEED 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
the negative (-) lead to terminal 2.
(c) Rotate the 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 revolution of
the speed sensor shaft.
If operation is not as specified, replace the sensor.
6. INSPECT SPEEDOMETER RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as the specified, replace the meter.
7. INSPECT TACHOMETER/ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will dam-
age the transistors and diodes inside.
When removing or installing the tachometer, be care-
ful not to drop or subject it to heavy shocks.
(b) Compare the tester and tachometer indications.

8. INSPECT TACHOMETER RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as specified, replace the meter.
9. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the main sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and receiver gauge needle moves toward the full side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
10. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as specified, replace the receiver
gauge.
11. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 3 and 2 for each
float position.
Float position mm (in.)Resistance (W)
F: Approx. 91.1 (1.36) ± 3 (0.12)Approx. 2.0 ± 1.0
1/2: Approx. 34.2 (2.06) ± 3 (0.12)Approx. 26.1 ± 3.0
E: Approx. 30.8 (5.31) ± 3 (0.12)Approx. 48.7 ± 1.0
If resistance value is not as specified, replace the sender
gauge.
