Sometimes the car has some ungrateful defects. Out of nowhere, it loses power and a light comes on on the dashboard . The driver stops, turns off the engine, starts again and the fault disappears, the light goes out. It works normally for two, three days, and then suddenly, it happens again. This is an example of an intermittent defect, which only occurs from time to time in very specific situations. When the car starts to present this type of problem, the driver finds himself in a complicated situation, as confidence in the vehicle is lost. After all, at any time it could go bad again, and who guarantees that it will go back to normal right away, just by turning it off and on again? When taking the car to the workshop, no defects are detected by the automotive diagnostic device, the scanner. And in the test run with the repairman, the defect does not appear. But just leave the workshop, drive four or five blocks and he'll come back.
At this point, the right thing to do is to turn around and go to the workshop with the bad car, to show the mechanic the defect. If possible, do not turn it off when you get there so that a diagnosis can be made with the scanner. In most cases, the device will give a clue as to what the problem may be, but it will take a few hours of investigation to determine the real cause of the defect. Usually intermittent defects are caused by electrical problems with the harness or Lithuania Phone Number malfunction of an electronic component, which scrambles the signal sent to the vehicle's electronic control unit, responsible for calculating and managing the fuel injection system. In modern vehicles, the sensors that capture data from the engine and automatic transmission are more precise, with increasingly lower tolerance levels, due to the laws on pollutant gas emissions and the greenhouse effect.
Therefore, any small voltage deviation can affect the proper functioning of the sensor and, consequently, the vehicle. Regardless of the number of electronic components the vehicle has, the proper functioning of the engine requires three elements in correct quantities and applied at the right time: air (oxygen), fuel and electricity (to produce a spark). The key to solving an intermittent defect begins with identifying which (or which) of these elements are missing at the time of the failure. However, it is necessary to drive the vehicle until the defect manifests itself, preferably with a scanner connected, to carry out measurements of the engine parameters. As it is intermittent, the defect can appear at any time, without prior warning. According to experts, this is the worst part of solving the defect. It can take hours, days, and even weeks just to view this data.
