Fuel

Consumption

Excessive

Probable Causes

• Diagnostic codes

• Misreading of fuel level

• Fuel leakage

• Fuel quality

• Quality of oil

• Engine accessories and transmission

• Coolant temperature

• Prolonged operation at idle speed

• Engine operating speed

• Air intake and exhaust system

• Cooling fan

• Reduced pressure of intake air

• Valve lash

Recommended Actions

Note:

The procedures have been listed in order of

probability. Complete the procedures in order.

Troubleshooting Test Steps

Values

Results

1. Diagnostic Codes

Note:

Certain diagnostic codes and/or event codes indicate the

cause of high fuel consumption.

A. Use the electronic service tool to check for active or logged
codes.

Diagnostic
codes

Result:

A diagnostic code is present.

Troubleshoot the diagnostic code and then verify that the
fuel consumption is normal. Refer to Troubleshooting, “Diag-
nostic Trouble Codes”.

Result:

A diagnostic code is not present.

Proceed to Test Step 2.

2. Misreading of Fuel Level

Note:

Misreading of the fuel gauge can give a false indication of

fuel consumption.

A. Monitor the fuel consumption over a period of 50 engine
hours.

Fuel level

Result:

Fuel consumption is normal for the operating

conditions.

Return the unit to service.

Result:

Fuel consumption is high for the operating

conditions.

Proceed to Test Step 3.
