Despite the fact that the design and principle of operation of the internal combustion engine have remained unchanged for more than a century, modern power plants are much different from their ancestors. Today's motors are the most complex technical structures, which include not only a mechanical, but also an electronic part. Therefore, such engines must be regularly diagnosed in order to prevent the development of any breakdown. In this process, many nuances should be taken into account, which we will talk about today.
At the moment, engine diagnostics are performed only in two cases. The first is when a driver buys a used car and wants to check how well its “heart” works. Well, the second case occurs when the motorist suspected any problems associated with the dynamics and behavior of the car, that is, signs indicating a malfunction of the motor.
As for theoperation, engine diagnostics are divided into the following categories.
- Identification of possible breakdowns and malfunctions visually (that is, by ear and by touch). This type of work is very popular with motorists, because it can be done independently, without the use of any expensive tools. However, it should be borne in mind here that such engine diagnostics only partially determines possible sources of breakdowns.

And now more about this. Masters in this type of work connect a scanner to the diagnostic connector (it is located under the hood), that is, a computer that checks the system for errors. It reads encrypted codes, monitors the value of various sensors. Thanks to this, computer equipment is able to determine the exact type of breakdown and indicate its source. Thus, this type of work allows you to most accurately determine the type and type of faults.
However, unfortunately, such devices are used only in service stations. The thing is that this equipment (it consists of a motor tester, multimeter, oscilloscope, scanner, pressure gauge and compression gauge) costs a lot of money. Moreover, only a professional master can use it correctly, since all these tools have a lot of nuances that should be considered when using. Therefore, it simply does not make sense to purchase diagnostic equipment for home purposes.
And finally, I would like to note a few more points that can be determined using special equipment in any modern car, be it a domestic VAZ or a Japanese Toyota. Engine diagnostics can show the characteristics and properties of the ignition system, as well as check its current condition. In addition, thanks to electronic equipment, it is possible to correct the engine control unit, thereby extending the life of the motor.

The car is a complex of complex components and mechanisms. No matter how automakers improve production technology and increase reliability, no one is immune from sudden breakdowns. This applies to all car enthusiasts. Both the owner of an expensive foreign car and a supported VAZ may encounter such a malfunction as engine tripping. Well, let's consider why the "check" is flashing on the car and the engine is troit
