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 >> 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 fuel level sensor unit. Refer to DI-25, "Fuel Level Sensor Signal Inspection [Gasoline
Engine Models]" or DI-26, "Fuel Level Sensor Signal Inspection [Diesel Engine Models]" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
