4. QUESTION 4
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES >> Check the fuel level sensor unit. Refer to DI-25, "CHECK FUEL LEVEL SENSOR UNIT" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
Electrical Components InspectionAKS005N5
CHECK FUEL LEVEL SENSOR UNIT
For removal, refer to FL-4, "FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY" .
Check Fuel Level Sensor Unit and Fuel Pump (Main)
Check the resistance between terminals 2 and 5.
*1 and *2: When float rod is in contact with stopper.

If the results of check are NG, check the fuel level sensor unit
and fuel pump (main) harness. Refer to DI-25, "
Check Fuel
Level Sensor Unit and Pump (Main) Harness" .
Check Fuel Level Sensor Unit and Pump (Main) Harness
Check continuity at following terminals.

If the results of check are NG, replace fuel pump assembly. If the
results of check are OK, replace fuel level sensor unit.
Check Fuel Level Sensor Unit (Sub)
Check resistance between terminals 1 and 2.
*1 and *2: When float rod is in contact with stopper.

5. CHANGE ENGINE OIL
1. Stop the engine.
2. Change engine oil. NOTE:
This symptom may occur when a large amount of gasoline is mixed with engine oil because of driving
conditions (such as when engine oil temperature does not rise enough since a journey distance is too
short during winter). The symptom will not be detected after changing engine oil or changing driving con-
dition.
>> INSPECTION END
6. CHECK FUEL PRESSURE
Check fuel pressure. (Refer to EC-99, "
