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.

●

If the results of check are NG, replace fuel pump assembly.

●

If the results of check are OK, replace fuel level sensor unit.

NOTE:
When replacing fuel level sensor unit, refer to 

FL-5, "FUEL LEVEL

SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY"

  in
