Check of serviceability of functioning of system of injection


1. Check reliability of fastening of electric connections, especially plugs of grounding of a chain of system of injection. Attentively examine all systems concerning functioning electric sockets. Violation of quality of electric contacts involves a set of problems and of more than a half of engine failures is at the bottom.
2. Check level of a charge of the battery – accuracy of management of structure of an air and fuel mix to a great extent depends on serviceability of functioning of RSM and the information sensors, defined including level of tension of their food.
3. Check a condition of a filtering element of an air purifier, – even partial violation of passableness of the air filter makes essential impact on profitability of fuel consumption and engine return (see. Head Routine maintenance).
4. Check serviceability of functioning of the fuel pump (see. Check of serviceability of functioning of fuel pump/pressure of fuel). If the safety lock of the pump fused, replace it new. If the new safety lock also fails at once, check chain electroconducting on existence of signs of short circuits (see. 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 on existence of a nagaroobrazovaniye and other pollution (in particular on sites near a butterfly valve). In case of identification of signs of pollution of the case of a throttle address to materials of Head of the Control system of the engine and make diagnostics of malfunctions of PCV and EGR systems. At strong pollution the case of a throttle is subject to replacement.

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

7. At the working engine serially hear by means of a stethoscope to each of injection injectors – the uniform poshchelkivaniye testifies to serviceability of functioning of an injector (see an accompanying illustration). 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 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 a suspected injector (see an accompanying illustration). Start the engine and check by means of a lamp all injectors. The uniform blinking of a lamp confirms serviceability of functioning of an injector.

9. Muffle the engine, disunite electric sockets of injectors and measure electric resistance of each of them (see an accompanying illustration). 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 Head of the Control system of the engine.
