At check of electronic system of injection of fuel operate as follows:
Check up reliability of connection of electric sockets. Infringement of electric connection in a socket results to failures in work of electronic system of injection of fuel.
Check up a condition and degree заряженности the storage battery because the engine management block (PCM) and gauges cannot work as appropriate amount at a food low voltage.
Check up a condition of a filtering element of the air filter. At its pollution the quantity of air arriving in cylinders of the engine therefore capacity of the engine will decrease decreases and the fuel expense will increase.
Check up work of the fuel pump. If the fuel pump does not work, check up serviceability of a safety lock in a feed circuit of the fuel pump. If the safety lock is serviceable, and the fuel pump does not work, check up a feed circuit of the fuel pump.
Check up the vacuum hoses connected to an inlet collector on absence of damages, defects and unreliability of their connection.
Remove a branch pipe of an air inlet from throttle knot and check up a condition in throttle knot on absence of adjournment of soot and other pollution, especially round throttle заслонки. In the presence of pollution check up systems of compulsory ventilation картера (PCV) and рециркуляции the fulfilled gases (EGR).
At work of the engine as a stethoscope serially put to each atomizer, check up their working capacity. If clicks are audible, means, electric chains
of management of atomizers are serviceable, however it is necessary to mean that internal pollution can break work of atomizers. In this case clean or replace atomizers.
In a case if the clicks published at work of an atomizer are not audible, disconnect an electric socket and measure resistance of an atomizer. If resistance of an atomizer differs from demanded, replace it.
If the atomizer does not work, but its resistance is in norm limits, check up serviceability of the block of engine management (PCM) and an electric feed circuit of an atomizer.
