Removal and installation of components of system of the central injection of Multec fuel

See the prevention at the beginning of pressure Sbrasyvaniye's section in a power supply system of petrol engines.

Fuel injector

Before finally affirming as opinion on an injector exit out of operation, try to add in fuel any of the automobile engines of additives approved by producers. Make sure also that the fuel tank is not polluted.


 PERFORMANCE ORDER

  1. Dump pressure in a power supply system (see Sbrasyvaniye pressure in a power supply system of petrol engines), then disconnect a negative wire from the battery.
  2. Weaken a collar and disconnect an inlet air line from a cover of the case of a throttle. Disconnect from a cover also vacuum hoses and hoses of ventilation of a case. Turn out fixing screws and uncover with a sealing ring the throttle case.
  1. Release a clamp and disconnect from an injector electroconducting.

  1. Turn out the fixing screw.
  1. Cнимите plate of fastening of an injector.

  1. Take an injector assembled with a sealing ring from a landing nest in the throttle case. Will throw out sealing rings, - at installation they is subject to replacement without fail.
  1. Installation is made upside-down, - do not forget to replace a sealing ring. Track, that the bolt of fastening of an injector was tightened with demanded effort.

Regulator of pressure of fuel

At the moment of drawing up of the real Management components of a regulator of pressure separately on the market of spare parts were not delivered. In case of failure replace the throttle case assembled. Despite basic possibility of dismantling and pro-cleaning of a regulator assort only as a last resort.


 PERFORMANCE ORDER

  1. Dump pressure in a power supply system (see Sbrasyvaniye pressure in a power supply system of petrol engines), then disconnect a negative wire from the battery.
  2. Weaken a collar and disconnect an inlet air line from a cover of the case of a throttle. Disconnect from a cover also vacuum hoses and hoses of ventilation of a case. Turn out fixing screws and uncover the throttle case assembled with a sealing ring.
  1. With marker mark the provision of a cover of a regulator concerning the throttle case. Turn out screws of fastening of a cover of a regulator.
  1. Uncover, take a saddle of a spring and a spring, take out a diaphragm, try to remember the adjusting provision of components. Remove all traces of dirt, check a diaphragm condition, - in case of identification of signs of wear or damage replace the throttle case.

    1 — the Diaphragm
    2 — the Spring
    3 — a spring Saddle
    4 — the Cover

  1. Installation is made upside-down. Track, that all fixture was tightened with demanded effort.

Step-by-step engine of system of stabilization of turns of idling

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. For the purpose of ensuring adequate access weaken a collar and disconnect an inlet air line from a cover of the case of a throttle. Disconnect from a cover air and vacuum hoses, turn out fixing screws and uncover the case together with a sealing ring.
  1. Release a clamp and disconnect electroconducting from the step-by-step engine established in a forward part of the case of a throttle.
  1. Turn out fixing screws and accurately take the electromotor from the case, - try not to damage a plunzher. Remove from the electric motor a sealing ring, - at assembly it is subject to replacement without fail.

  1. Installation is made upside-down. For check of serviceability of functioning of system of stabilization of turns of idling measure size of a vystupaniye of a plunzher (And) from the electric motor, - the result of measurement should make no more than 28 mm.

Sensor of situation (potentiometer) of a butterfly valve (TPS)

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery. Also disconnect electroconducting from the TPS sensor.
  1. Turn out fixing bolts and remove the TPS sensor from the throttle case.
  1. Installation is made upside-down. Track correctness of input of a potentiometer in gearing with a butterfly valve axis. Before a vvorachivaniye of fixing bolts grease their carving part with anaerobny hermetic. Having tightened bolts with demanded effort, connect to the sensor electroconducting.

The sensor of temperature of cooling liquid (ECT)

The sensor of temperature of cooling liquid will screw in a back part of the inlet pipeline. The description of procedures of removal and sensor installation – see. Check of serviceability of functioning, removal and installation of electric components of a chain of management of system of cooling of the engine.

The sensor of absolute pressure in the pipeline (MAP)

The MAP sensor is fixed on a partition of an impellent compartment, to the left of the throttle case.


 PERFORMANCE ORDER

  1. Switch off ignition, disconnect from the sensor electroconducting and a vacuum hose. The sensor can be removed now from an arm.
  2. Installation is made upside-down.

Sensor of provision of a cranked shaft (CKP)

 PERFORMANCE ORDER

  1. The sensor is established on a back wall of the block of cylinders and access to it is possible from under the car. Cock the parking brake, поддомкратьте a front of the car and establish it on props.
  2. Walk on electroconducting from the sensor, liberating a plait from intermediate clamps and remembering a route of its laying. Disunite the contact socket, - the sensor acts in film together with a part of a plait.
  1. Turn out a fixing bolt and remove the sensor.
  1. Installation is made upside-down. Track, that the fixture was tightened with demanded effort. Make sure of correctness of laying of a plait.
  2. In end measure distance between the sensor and a gear rotor on a crankshaft pulley, - if the result exceeds 1.0 ± 0.7 mm, replace a basic arm of fastening of the sensor.

Sensor of a detonation (KS)

The sensor of a detonation is established on a back wall of the block of cylinders and access to it is possible from under the car.

 PERFORMANCE ORDER

  1. Cock the parking brake, поддомкратьте a front of the car and establish it on props.
  2. Walk on electroconducting from the sensor, liberating a plait from intermediate clamps and remembering a route of its laying. Disunite the contact socket, - the sensor acts in film together with a part of a plait.
  3. Turn out a fixing bolt and remove the sensor.
  4. Installation is made upside-down. Before installation make sure of absoluteness of purity and dryness of interfaced surfaces. Tighten fixture with demanded effort. Track correctness of laying of electroconducting.

Electronic module of engine management (ECM)

ECM is behind the storage battery in the left part of an impellent compartment.

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery and remove both screen wipers (see. Head Onboard electric equipment).
  2. Remove from the module a protective cover.
  3. Having pulled up, liberate the module from a basic arm and disconnect from it electroconducting.

Before installation of the module it is possible to make cleaning of memory of the processor for the purpose of removal from it the written-down diagnostic codes in the conditions of a car-care center workshop.

  1. Installation is made upside-down.

Relay of system of injection

 PERFORMANCE ORDER

  1. The relay of system of injection is in the assembly block located in an impellent compartment.
  1. Remove from the assembly block a cover. The relay of system is painted in purple color. Make sure that ignition is switched off, then liberate the relay from a block.

Central air sensor switch

The sensor switch of system of the conditioner will screw in one of lines of a refrigerator path and it can not be removed without a preliminary discharge of system (see. Head of System of cooling, heating). In view of the sensor switch told replacement it is necessary to make in the conditions of a car-care center workshop.
