Inspection
Speedometer
1. Using a speedometer tester, check the speedometer for ai-
lowable indication error, and check the operation of the
odometer. Replace if necessary.
2. Check the speedometer for fluctuation and/or abnormal
noise.
Caution
l If significant fluctuation occurs or the speedome-
ter does not move at all, remove the speedometer
cable. If it is normal, replace the speedometer as-
sembly.
l Tire wear and improper inflation will Increase
speedometer error.
Tachometer
1. Connect a test tachometer to the engine, and start the
engine.
2. Check the tachometer for allowable indication error. Replace
if necessary.
Caution
l When removing or installing the tachometer, do not
drop it or subject it to sharp shocks.
Fuel gauge
1. Remove the instrument cluster. (Refer to page T-69.)
2. Apply battery voltage to terminal 2L and ground terminal 2E.
3. Connect the red lead of the
SST to terminal 1C and the
black lead to a negative battery terminal.
4. Set the
SST to the resistance values shown in the figure.
5. Verify that the needle indicates the correct values.
Caution
l Continue the above checks for at least two minutes
each to correctly judge the condition.
l The allowable indication error is twice the width of
the needle.

Cautlon
l Continue the above checks for at least two minutes
each to correctly judge the condition.
l The allowable indication error is twice the width of
the needle.
Speed sensor
1. Remove the instrument cluster.
2. Check continuity between terminals 2A and 2F while rotat-
ing the speedometer cable shaft.
3. If there are not four pulses per shaft rotation, replace the
speed sensor.
WATER THERMOSENSOR
Removal / Installation
1. Remove the connector.
2. Remove the thermosensor.
3. Install in the reverse order of removal.
Inspection 1.
Remove the sensor.
2. Place the sensor in water.
3. Heat the water gradually, and check the resistance of the
sensor with an ohmmeter. 4.
If the resistance is not as specified, replace the sensor.
Resistance: 190-2603 at 5O*C (122OF)
