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.

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

(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.

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.
