6. CHECK FUEL LEVEL SENSOR
1 CHECK FUEL LEVEL SENSOR.
1) Remove the fuel level sensor. <Ref. to
FU(H4SO)-64, REMOVAL, Fuel Level Sen-
sor.> or <Ref. to FU(H4SOw/oOBD)-61,
REMOVAL, Fuel Level Sensor.><Ref. to
FU(H4DOSTC)-61, REMOVAL, Fuel Level
Sensor.>or <Ref. to FU(H6DO)-67,
REMOVAL, Fuel Level Sensor.>
2) Measure the resistance between the fuel
level sensor terminals when setting the
float to FULL and EMPTY position.
Terminals
No. 3 — No. 6
Is the measured value within the specified
range?
2 CHECK FUEL SUB LEVEL SENSOR.
1) Remove the fuel sub level sensor. <Ref. to
FU(H4SO)-65, REMOVAL, Fuel Sub Level
Sensor.> or <Ref. to FU(H4SOw/oOBD)-
62, REMOVAL, Fuel Sub Level Sensor.> or
<Ref. to FU(H4DOSTC)-62, REMOVAL,
Fuel Sub Level Sensor.> or <Ref. to
FU(H6DO)-68, REMOVAL, Fuel Sub Level
Sensor.>
2) Measure the resistance between the fuel
sub level sensor terminals when setting the
float to FULL and EMPTY position.
Terminals
No. 1 — No. 2
Is the measured value within the specified
range?
3 CHECK HARNESS BETWEEN FUEL SUB
LEVEL SENSOR AND COMBINATION
METER.
1) Disconnect the connector from the combi-
nation meter.
2) Measure the resistance between the fuel
sub level sensor harness connector termi-
nal and combination meter harness con-
nector terminal.
Connector & terminal
Standard meter:
(R59) No. 1 — (i10) No. 3:
Luminiscent (LHD):
(R59) No. 1 — (i11) No. 15:
Luminiscent (RHD):
(R59) No. 1 — (i10) No. 17:
Is the measured value less than the speci-
fied value?
COMBINATION METER SYSTEM
