The Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or VariesEKS00EHG
1. CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving and just before or soon after stopping.
Does the indication value vary only during driving and just before or soon after 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.
The Fuel Gauge Does Not Move to FULL positionEKS00EHH
1. QUESTION 1
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. QUESTION 2
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 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 or NO
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 or NO
YES >> Check fuel level sensor unit. Refer to DI-30, "FUEL LEVEL SENSOR UNIT CHECK/GASOLINE
ENGINE MODELS" or DI-30, "FUEL LEVEL SENSOR UNIT CHECK/DIESEL ENGINE MOD-
ELS" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
