Fault text

Tank fill level, plausibility

Fault description

Fuel Level Sensor 'A' Circuit Range/Performance

Condition for fault identification

Test condition:

Excess mechanical resistance in the level sensor causes the level signal to change too slowly relative to engine fuel consumption, leading to generation of a fault memory entry Terminal condition: Terminal 15, engine on

Voltage condition: none

Condition for fault memory entry

20 liters of fuel consumption required

Action in service

Check level sensor data directly at flange

Check variation in sensor data by rocking / knocking on the tank

Carefully open the tank flange, check for stiction in the float lever

Replace the fuel level sensor only if stiction is found in the float lever (distorted sensor lever, bearing resists motion)

Fault effect and breakdown warning
