Description
The fuel level sensor unit and fuel pump detects the approximate fuel level in the fuel tank and transmits the fuel level signal to the combination meter.
Component function check
1.Combination meter input signal
Does the data monitor value approximately match the fuel gauge indication? YES >> Inspection End.
NO >> Replace combination meter. Refer to MWI-77, "Removal and Installation".
Diagnosis procedure
Regarding wiring diagram information, refer to mwi-28, "wiring diagram".
1.Check fuel level sensor circuit
Is the inspection result normal? Yes >> go to 2.
No >> repair or replace harness or connector.
2.Check fuel level sensor ground circuit
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace harness or connector.
3.Check installation condition
Check fuel level sensor unit installation, and check whether the float arm interferes or binds with any of the internal components in the fuel tank.
Is the inspection result normal? Yes >> inspection end.
No >> install the fuel level sensor unit properly. Refer to fl-6, "removal and installation".
Component inspection
1.Remove fuel level sensor unit
Remove the fuel level sensor unit. Refer to fl-6, "removal and installation".
>> Go to 2.
2.Check fuel level sensor unit
Check the resistance between fuel level sensor unit and fuel pump.
*: When float rod is in contact with stopper.
Is inspection result ok? Yes >> inspection end.
No >> replace fuel level sensor unit and fuel pump. Refer to fl-6, "removal and installation".
