Condition for fault identification

Test condition:

The fault is recognized when the tank content that the DME calculates from the injection signal deviates too starkly from the actual gauge reading appearing in the instrument cluster.

Potential problem source(s):

• Fuel level sensor sticking
• Fuel level sensor mechanically damaged
• Float on fuel level sensor is damaged
• Frequent refueling with quantities of less than 5 liters (as with rental vehicles)

Terminal condition: none

Voltage condition:

• Onboard electrical system voltage between 9 V and 16 V

Temperature condition:

• None

Time condition:

• None

Other conditions:

• Engine on
• No fault related to tank fuel-level sensor is currently present
• At least 20 liters of fuel must be consumed without refueling (multiple cycles possible)
