Attention:
- Cover all adjacent parts with rags to prevent fuel from spilling on them.
- After removing the high-pressure fuel pipes, do not allow dirt or foreign materials to enter them. When installing the fuel pipes, tighten the nuts to the specified torque.
- Remove and install parts strictly in the sequence shown below to avoid fuel leaks.
- The number of times high-pressure fuel pipes can be reused without losing their reliability is limited. Only five times are old high-pressure pipes allowed to be reinstalled after they have been removed. After the sixth removal of high-pressure pipes, they must be replaced.
- When connecting the fuel hoses, refer to the figure "Location of fuel system components in the engine compartment".
- If the injector has been replaced, the identification code of the new injector should be programmed into the engine control unit memory.
1. Disconnect the cable from the negative terminal of the battery.
2. Follow the procedures in the "Before Repairing" section.
3. Disconnect the connectors of the following items:
- Camshaft position sensor.
- Coolant temperature sensor.
- Fuel accumulator pressure sensor.
- Injectors.
4. Remove the parts in the numbering sequence shown in the assembly drawing "Removing and installing injectors".
5. Installation of parts is carried out in the reverse order of removal.
6. Perform the procedures specified in the "After Repair Work" section.
Checking the injector
1. Disconnect the cable from the negative terminal of the battery.
2. Disconnect the connector from the injector and, using an ohmmeter, check the resistance between the injector terminals (at a temperature of 20°C).
- Resistance - 0.225 Ohm
If the resistance between the injector terminals differs from the specified value, replace the injector.
Removal and installation of injectors.
1 - fuel return hose,
2 - high pressure fuel pipes,
3 - nozzle holder,
4 - nozzle.
