Fault codes for fuel injector
The fuel injectors (2) are an integral injector and solenoid assembly mounted in the cylinder head. The injectors are actuated by rocker arms and the camshaft. The timing and duration of fuel delivery is controlled by the solenoid, which is directly controlled by the ECU module. The ECU is connected to the fuel actuators by means of connector X471, which is connected directly to the side of the cylinder head.
| Injector | Connector X471 pins | Connector X192 pins |
| Fuel actuator 1 L-34 | Pins A & F | Pins 35 & 24 |
| Fuel actuator 2 L-35 | Pins G & N | Pins 26 & 25 |
| Fuel actuator 3 L-36 | Pins B & F | Pins 34 & 24 |
| Fuel actuator 4 L-37 | Pins M & N | Pins 27 & 25 |
| Fuel actuator 5 L-38 | Pins E & F | Pins 33 & 24 |
| Fuel actuator 6 L-39 | Pins H & N | Pins 28 & 25 |
These circuits are monitored by the ECU module; in the event that a fault occurs with the sensor itself or the wiring to the sensor, a fault code will be displayed to the operator.
