- Control signal wire shorted to ground
- Open circuit in the control signal wire
- Defective injector

What you can do
- 1Switch off the ignition and check the connector to the cylinder 1 injector for play, contact resistance and oxidation
- 2With a multimeter, check that the control wire to the injector is not broken and not shorted to ground or voltage
- 3If the injector and wiring are fine, the fault may be in the control module. Clear the code and see whether it returns
- 4If the fault remains, have a workshop replace the cylinder 1 injector or check the control module
