Check of serviceability of functioning of injectors

The elementary way of check of serviceability of functioning of injectors of injection of fuel is their listening, - at the working engine injectors should publish rhythmical пощелкивание. Check can be made by means of a mechanical stethoscope, or contact way, by means of a screw-driver. Published with the electromagnetic valve щелканье confirms serviceability of functioning of a working contour of an injector and the processor of management of the power supply system. Serially check up each of injectors.

At performance of procedures of service in a motor compartment at the working engine observe extreme care, - try not to touch moving components (приводные belts, крыльчатка the fan, etc.) and not to suppose hit in them of hair and clothes elements.

The analysis of results of check

All injectors regularly click


1. If all injectors regularly click and, nevertheless, there are suspicions on presence of infringements of functioning of the power supply system, continue diagnostics.
2. Check up the pressure head characteristic of the fuel pump (see more low).
3. Check up ignition system. Serially disconnecting (and connecting back) ВВ wires from each of spark plugs at the idling engine, try to localise on absence of infringement of stability of turns the faulty cylinder.
4. Remove an injector of injection of fuel in the suspected cylinder and transfer it on a workbench (it is possible to remove a fuel highway in gathering). For check эпюры injection connect to an injector a line of giving of fuel and for short time submit on its plugs pressure 12 In a direct current (grounding is carried out through the injector case): there should be an emission конусовидной fuel streams through a valve nozzle. The faulty injector is subject to replacement.

One or several injectors do not publish clicks


1. Prepare a special lamp-sampler. Switch off ignition and disconnect electroconducting from an injector subject to check. Connect a lamp-sampler to a contact socket of a plait of electroconducting of an injector and start the engine: the lamp blinking confirms serviceability of giving on an injector of operating pressure.

2. If infringements in power supplies giving it is not revealed, measure resistive resistance of an injector. Compare result of measurement to requirements of Specifications (for engines with normal всасыванием the rating value lays within a range 13 16 Ohm, at 20 With, for engines with a turbo-supercharging the demanded range makes 2 3 Ohm [at the same temperature]).

3. If during testing by a lamp-sampler signs of failures in giving of operating pressure are revealed, it is necessary to check up a condition of a corresponding electric contour. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped by a security code before to disconnect the battery make sure that have a correct combination for audiosystem input in action! Disconnect from an injector a lamp-sampler. Also disconnect electroconducting from PCM. Check up an electroconducting condition on a chain site between PCM and an injector: resistive resistance between corresponding contacts of sockets should make nearby 5 Ohm. At negative results of check make necessary regenerative repair of electroconducting.

4. If the chain as it should be, hence, takes place internal refusal PCM and the management module it is necessary to replace.
