Hva betyr feilkoden?
The ECM drives the fuel pressure control valve with pulse width. If the control signal is too low, for example through a break or a short to ground, fault code ECM-1822 is set.
Mulige årsaker
- Control signal wire shorted to ground
- Open circuit in the control signal wire
- Supply wire shorted to ground
Hva du kan gjøre
- 1Switch off the ignition and check the connector to the fuel pressure control valve for play, contact resistance and oxidation
- 2With a multimeter, check that the control and supply wires to the valve are not broken and not shorted to ground
- 3If you have a diagnostic tool: activate the fuel pressure control valve and check that it responds
- 4If the fault remains, have a workshop check the valve and its wiring
Symptomer du kan merke2
