CHECK FUEL LEVEL SENSOR
Check fuel level sensor units. Refer to
DI-18, "FUEL LEVEL SENSOR UNIT"
.
OK or NG
OK
>> 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. Repair or replace malfunctioning part, if neces-
sary.
NG
>> Replace fuel level sensor unit and fuel pump (main) or fuel level sensor unit (sub).
Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or Varies
NKS000KQ
1.
CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or at the instant of stopping.
Does the indication value vary only during driving or at the instant of stopping?
YES
>> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO
>> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
Fuel Gauge Does Not Move to FULL position
NKS000KR
1.
QUESTION 1
Does it take a long time for the pointer to move to FULL position?
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES
>> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the characteristic of the fuel gauge.
NO
>> GO TO 3.
3.
QUESTION 3
Is the vehicle parked on an incline?
YES
>> Check the fuel level indication with vehicle on a level surface.
NO
>> GO TO 4.
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-18, "FUEL LEVEL SENSOR UNIT"
NO
>> The float arm may interfere or bind with any of the components in the fuel tank.
