Fault code: 54019 SCANIA

Error identification:

Circuit monitoring shows implausible values for the solenoid valve for fuel quantity to the front bank, cylinders 1-3, compared with other solenoid valves.

Cause:

The solenoid valve is faulty or the circuit is short circuited to ground.

Notes:

The engine runs very unevenly if the fuel supply to all cylinders is not working correctly.

Action:

Check the circuit components, harness-to-harness connectors and electrical cables. Clear the fault code memory, start the engine and rev it up. Check that the engine is running smoothly and reacts normally to the accelerator. Renew the solenoid valve if the fault persists.
