Check of serviceability of functioning of system of injection


See preventions at the beginning of the Section Dropping Pressure in a power supply system.

1. Check reliability of fastening of electric connections, especially plugs of grounding of a chain of system of injection. Attentively examine all electric sockets concerning functioning of system. Violation of quality of electric contacts involves a set of problems and more than a half of engine failures is the reason.
2. Check battery charge level. Accuracy of management of composition of air and fuel mix to a great extent depends on serviceability of functioning of RSM and information sensors defined including, and the level of tension of their food.
3. Check a condition of the filtering air cleaner element, - even partial violation of passability of the air filter has essential impact on profitability of fuel consumption and efficiency of return of the engine (see the Head Nastroyki and routine maintenance).
4. Check serviceability of functioning of the fuel pump (see the Section Check of Serviceability of Functioning of the Fuel Pump, measurement of pressure of fuel). If the safety lock of the pump fused, replace it new. If the new safety lock fails also at once, check a chain electrical wiring for existence of signs of short circuit (see the Head Onboard electric equipment).
5. Check a condition of the vacuum hoses connected to the inlet pipeline.
6. Disconnect an air sleeve from the case of a throttle and check the last for existence of a nagaroobrazovaniye and other deposits (in particular on sites near a butterfly valve). In case of identification of signs of pollution of the case of a throttle, address to the Head's materials Engine management and make diagnostics of malfunctions of PCV and EGR systems. At strong pollution the case of a throttle is subject to replacement.

Walls of a throttle chamber, butterfly valve and its axis on the considered models of cars are covered with a protective film which should not try to be removed in order to avoid casual damage of components.

7. At the working engine serially listen to each of injection injectors by means of a stethoscope, - the uniform poshchelkivaniye testifies to serviceability of functioning of an injector. In the absence of near at hand stethoscope, use a long screw-driver, simply pressing a tip of her sting to the case of an injector and being guided by the vibrations transferred on the handle.

8. At identification of violations of functioning of an injector it is necessary to use a special lamp sampler for diagnostics of injectors (ask in shops of automobile accessories). The lamp is connected to the electric socket of the suspected injector. Start the engine and check all injectors by means of a lamp. The uniform blinking of a lamp confirms serviceability of functioning of an injector. Otherwise the car should be driven away on car repair shop for more detailed diagnostics.

9. Kill the engine, disunite electric sockets of injectors and measure the electric resistance of each of them. Compare results of measurements to requirements of Specifications. In case of need replace the failed knot.

10. Additional information on diagnostics of a condition of system of injection contains in the Head Engine management.
