Hva betyr feilkoden?
The injectors are driven by the injector driver stage, and the code is set when something in that circuit is faulty. The cause may be defective injectors, a defective relay or driver stage, a short-circuit, an open circuit or contact resistance. The engine may then not fire on every cylinder, and it may not start.
Mulige årsaker
- Defective injectors
- Defective injector driver relay
- Defective injector driver stage
- Circuit shorted to ground or to supply voltage
- Open circuit in the circuit
- Contact resistance
Hva du kan gjøre
- 1Check the connectors to the injectors and the control module, looking for contact resistance and oxidation.
- 2With a diagnostic tool, run the engine at idle and switch off the injectors one at a time. Note any that leave engine speed unchanged.
- 3With a multimeter, check that the wires between the connectors and the injector driver stage are not broken.
- 4If the wiring is fine, the injector driver stage needs replacing. Have a workshop do this.
