INSPECTION
1. 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.
If error is excessive, replace the speedometer.
Standard indicationAllowable range
2018 − 24
4038 − 44
6058 − 66
8078 − 88
10098 − 11 0
120118 − 132
2. INSPECT NO.1 VEHICLE SPEED SENSOR OPERA-
TION
(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) Revolve shaft.
(d) Check that there is voltage changer from approx. 0 V to 11 V or more between terminals 3 and 2.
HINT:
The voltage change should be 4 times per each revolution of
the No.1 vehicle speed sensor shaft.
If operation is not as specified, replace the sensor.
3. INSPECT TACHOMETER ON−VEHICLE:
(a) Connect a tune− up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside.When removing or instal-
ling the tachometer, be careful not to drop or subject it to
heavy shocks.
(b) Compare the tester and tachometer indications.
If error is excessive, replace the tachometer.

If error is excessive, replace the voltemeter.
5. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, and check that the receiver gauge needle indicates EMPTY.
(c) Connect terminals 4 and 5 on the wire harness side con- nector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights up and the receiver gauge needle moves towards 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.
6. INSPECT FUEL RECEIVER GAUGE RESISTANCE

Measure the resistance between terminals 4 and 5.
Float position: mm (in.)Resistance (Ω )
F: Approx. 15.0 (0.591)Approx. 3.0
E: Approx. 200.0 (7.874)Approx. 110.0

(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 5 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminals 1 and 5
through a 3.4 W test bulb, and check that the bulb lights
up.
HINT:
It will take a short time for the bulb to light up.
