Attention! Maintenance of the injection system is carried out in a car service. It is independently allowed to change the sensors and devices of the injection system.
Nozzle
1. Decompress the fuel system and disconnect the battery from the ground.
2. Remove the air duct from the upper section of the throttle pipe, disconnect the hoses from the upper section, unscrew the screws and remove the upper section.
3. Remove the nozzle in accordance with the photo.
4. Installation is carried out in the reverse order. Replace injector o-rings.
Fuel pressure control
Attention!
- The fuel pressure regulator is changed along with the upper section of the throttle pipe.
- The regulator may be disassembled for cleaning, however, the pressure regulator should only be disassembled if absolutely necessary.
5. Decompress the fuel system and disconnect the battery from the ground.
6. Remove the top section of the throttle body by disconnecting the hoses and removing the screws.
7. Mark the position of the regulator cover relative to the throttle pipe, unscrew the screws (see photo) and remove the cover. Remove spring and diaphragm (see photo).
8. Wash the parts and check their condition.
9. Reassembly in reverse order
Electric drive of switching of idling
10. Disconnect the battery from the mass, remove the upper section from the throttle pipe.
11. Remove the actuator by unplugging the connector and unscrewing the screws (see photo).
12. Installation is carried out in the reverse order. When installing, make sure that dimension A does not exceed 28mm to avoid breaking the electric drive motor plunger (see photo). If necessary, gently push the plunger into the actuator housing.
Throttle Angle Sensor
13. Disconnect the connector from the sensor, which is located on the left side of the throttle pipe, unscrew the screws and remove the sensor (see photo). The sensor screws are screwed onto the fixing compound.
Intake manifold pressure sensor (MAP sensor)
14. The sensor is mounted with a bracket on the bulkhead of the engine compartment, to the left of the throttle pipe (see photo).
Crank angle sensor
15. The sensor is mounted in the front of the cylinder block, on the side of the partition of the engine compartment. Access to the sensor is provided from below
16. Disconnect the sensor connector from the harness, remove the sensor wire from the brackets.
17. Turn away a bolt and remove the gauge (see photo).
18. When assembling, check the gap between the end of the sensor and the tooth on the crankshaft pulley, which should be 1.0±0.7 mm. If the gap is not correct, replace the sensor bracket.
Knock sensor
19. The sensor is mounted at the rear of the cylinder block. Access to the sensor is provided from below.
20. Disconnect the sensor connector from the harness, remove the sensor wire from the brackets.
21. Turn away a bolt and remove the gauge.
Processor engine block
22. The unit is mounted next to the battery.
23. Disconnect the battery from the ground. Remove the cover from the block. Remove the unit from the bracket and disconnect the connector.
Attention! The processor unit of the engine is changed in a car service, as it needs to be recoded.
Fuel pump relay
24. The relay is located in the mounting block, which is mounted in the engine compartment.
25. Remove the cover and remove the relay (magenta relay housing).
