Fuel Level Sensor Unit Inspection
EKS00FYB
FUEL LEVEL SENSOR UNIT
The following symptoms do not indicate a malfunction.
●
Depending on vehicle position or driving circumstance, the fuel in the tank shifts and the indication may
fluctuate.
●
If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
●
If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction
resulting in a change of reading.
LOW-FUEL WARNING LAMP
Depending on vehicle posture or driving circumstances, the fuel level in the tank varies, and the warning lamp
ON timing may be changed.

Fuel Gauge Fluctuates, Indicates Wrong Value, or Varies
EKS00FYC
1.
CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or just before or just after stopping.
Does the indication value vary only during driving or just before or just after stopping?
YES
>> The fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO
>> Ask the customer in detail about the situation when the symptom occurs. Refer to
Fuel Gauge Does Not Move to Full-position
EKS00FYD
1.
CHECK POINTER MOVEMENT TO FULL-POSITION
Does it take a long time for the pointer to move to full-position?
YES or NO
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
CHECK IGNITION SWITCH POSITION
Was the vehicle fueled with the ignition switch ON?
YES or NO
YES
>> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time for the
pointer to move to full-position because of the characteristic of the fuel gauge.
NO
>> GO TO 3.
3.
OBSERVE VEHICLE POSITION
Is the vehicle parked on an incline?
YES or NO
YES
>> Check the fuel level indication with vehicle on a level surface.
NO
>> GO TO 4.
4.
CHECK POINTER MOVEMENT TO EMPTY-POSITION
During driving, does the fuel gauge move gradually toward empty-position?
YES or NO
YES
>> Check the fuel level sensor unit. Refer to
DI-23, "FUEL LEVEL SENSOR UNIT CHECK"
NO
>> Check fuel level sensor unit installation, and determine whether the float arm interferes or binds
with any of the internal components in the fuel tank.
