Replacement of the Fuel Gauge Unit
1.
Remove the fuel gauge unit. (03W505)
Caution
Since the fuel gauge unit is mounted to the side of the tank,
drain the fuel first. The in-tank filter of the fuel gauge unit
should be handled carefully because there is the danger of the
filter coming out of position.
2. When installing the fuel gauge unit, be careful not to
bend the float arm.
3. After installation, confirm that the unit is securely
grounded.

TEMPERATURE GAUGE INDICATION TEST
1.
Disconnect the wiring connector from the water tempera-
ture gauge unit inside the engine compartment.
2. Connect a resistance to the connector, and then confirm
the gauge indications.
Indication point Resistance value
(1) 115°C (239°F) 23.8 52
(2) 70°C (158°F) 104a
WATER TEMPERATURE GAUGE CONTINUITY TEST
Measure the resistance value between the terminals with an
ohmmeter.
Resistance value . . . . . . . . . . . . . . . .
Approx. 55 s2
NOTE
If the resistance value is extremely small, there may be a
short in the coil; if it is extremely large, there may be a
broken wire or some other problem in the coil. In either case,
replace the gauge.
WATER TEMPERATURE GAUGE UNIT OPERATION
CHECK
Measure the resistance with the gauge unit in hot water at
,7O”C (158°F).
Resistance value . . . . . . . . . . . . . . . . . . . . . . . 104 Q
Caution
The gauge unit should be held with its housing 3 mm (. 12 in.)
away from the surface of the hot water.
