Check of serviceability of functioning of system of electronic injection

See preventions at the beginning of pressure Sbrasyvaniye's Section in a power supply system.


1. Check reliability of fastening of electric connections of a chain of system of injection, giving particular attention to a condition of plugs of grounding. 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 ESM and the information sensors, defined, including, and level of tension of their food.
3. Check a condition of a filtering element of an air purifier (see. Head of Control and routine maintenance of the car), – even partial violation of passableness of the air filter makes essential impact on profitability of fuel consumption and efficiency of return of the engine.
4. If the safety lock of system of injection is beaten out, replace it, – if the new safety lock also fails at once, address to schemes of electric connections (see. Onboard electric equipment) also check the corresponding electric chain on existence of signs of short circuit on weight.
5. Check connecting air purifier and the inlet pipeline an air sleeve on existence of signs of development of the leaks conducting to pauperization of an air and fuel mix. Also check a condition of the vacuum hoses connected to the inlet pipeline.
6. Disconnect the air sleeve going from the case of a throttle and check the last on existence of traces of a nagaroobrazovaniye and other deposits (in particular on sites near a butterfly valve). In case of identification of signs of pollution of a throttle, address to materials of Head of the Control system of the engine and decrease in toxicity of the fulfilled gases and make diagnostics of malfunctions of PCV and EGR systems. Process a throttle one of types of the special cleaning aerosols suitable for the use on equipped with catalytic converters and oxygen sensors of cars, wipe the processed surfaces pure rags.
7. At the working engine serially hear by means of a stethoscope to each of injectors, – the uniform poshchelkivaniye testifies to serviceability of functioning of an injector (address to 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 signs of violation of functioning of an injector it is necessary to use a special lamp sampler (ask in shops of automobile accessories). The lamp is connected to the electric socket of a suspected injector. Start the engine and test a lamp all injectors. The uniform blinking of a lamp confirms serviceability of functioning of a component. Otherwise the car should be driven away on car repair shop for more detailed diagnostics.
9. Muffle the engine, disunite electric sockets of injectors and measure electric resistance of each of them (address to an accompanying illustration). Compare results of measurements to standard requirements, – demanded value makes 12-16 Ohm. Faulty injectors are subject to replacement.
10. Check self-diagnostics system on existence of the codes which were stored in her memory of malfunction (see. Head of the Control system of the engine and decrease in toxicity of the fulfilled gases).
11. It is necessary to charge performance of more detailed diagnostics of a condition of system to specialists of the car-care center, having all (rather expensive) equipment necessary for this purpose.
