What does Scania EMO fault code 514 mean?

Open circuit detected in the injector solenoid valve or in the electrical cables to the injector.

What causes Scania DTC 514?

The electrical cable or solenoid valve for the injector on cylinder 2 is probably defective.

What are the symptoms?

The fault only occurs when the engine is running. The control unit continuously tries to use the injectors irrespective of malfunctions. Engine power is affected to different degrees depending on how many injectors are faulty.

How to fix Scania EMO fault code 514?

  1. Run Safety precautions for the fuel system.
  2. Disconnect the electrical cable connections from the control unit and from the solenoid valve on the defective injector.
  3. Measure the resistance across the solenoid valve.
  4. Check the electrical cable pin connections in the switch to the control unit and the cable grommet in the cylinder head.
  5. Measure the resistance between the two loose ends of the positive cable and the negative cable.
  6. If the operating time since the fault code was generated exceeds 10 hours, drain the EGR cooler as there is a risk that condensation forms in the air-cooled EGR cooler when the EGR system has been switched off.
  7. Drain according to the instructions in Workshop Manual, subgroup 01-65.
