Diagnostic trouble code (DTC) information

Condition 

Information about the fuel level in the fuel tank is used to determine whether there are leaks during leak diagnosis.

If the control module detects diagnostic trouble code (DTC) ECM-4050 (fault in the fuel level sensor) and ECM-400C (leakage in the fuel tank system), diagnostic trouble code (DTC) ECM-405C is also stored. The diagnostic trouble code (DTC) for the fault is stored in the rear electrical module.

Substitute Value 

None.

Possible Source 

Faulty signal: 

• Fault in the circuit for the fuel level sensor or faulty function (rear electrical module).

Fault symptom[s] 

• Gauges/Fuel level not accurate/Value too low
• Gauges/Fuel level not accurate/Value too high
