What do you need to know if Check engine light is on?
Usable state depends on the condition of the car engine. Sometimes it is broken due to improper usage, and sometimes for other reasons. In such cases, we can observe the Check engine light on the panel. The best solution in this case is to contact the service center immediately, where the professional mechanics will run a computer diagnostics of your car. But if you want to understand what the problem is, this article is for you.
Most cases of engine breakdown are connected with wear of pistons. As a result, fuel consumption increases. Engines running on diesel fuel are fundamentally different from those that run on gasoline. For example, diesel engines are often repaired because of the pistons damage, as they can burn through. If you suddenly notice the above symptoms, be sure the problem will be in the engine physical damage.
Oil and fuel
For proper operation, the engine requires oil. It must be changed from time to time. During the mechanisms operation, the surfaces that are in sliding with each other without lubrication are very easily damaged. But the oil can quickly become dirty. If so, the parts wear out faster. As a result, engine seizure can be expected. After such a breakdown you will have to make costly repairs.
A driver should remember that the lack of oil always causes serious engine damage. And if your car is stalled, this is not the worst option. If such a situation occurred, it is necessary to wait until the engine cools down. While waiting, you should check the level in the oil tank with a special probe. Another mistake is to use low-quality and cheap oil.
It is often difficult to start the engine in strong frost. This is due to increased viscosity, especially mineral. In this case, you would better use synthetic motor oil, which copes with temperature changes very well.
Owners of diesel-powered cars should obligatory remember that the slightest impurities in the fuel may cause serious damage to the pump and damage the nozzle. Perhaps, some dust fell in the fuel tank, and then a pump will be broken and Check engine light will be on.
Operation mode and other factors
If the driver accelerates rapidly and permanently stops his car sharply, it will lead to rapid wear of vehicle parts. If most of the time the engine operates in one mode, it will cause a positive impact on both the stability and the term of its operation life.
Substandard car maintenance at service stations is another reason of unpleasant breakdowns. It is impossible to notice it immediately, but after the first thousand of kilometers a Check engine light will be on indicating a malfunction. In this case, we must first pay attention to engine temperature, as it can simply be overheated.
Sometimes the problem lies in the cooling system, as old hoses may crack. This leads to coolant loss and subsequent engine overheating.
As a result of water ingress into the cylinder, a so-called water hammer is occurred. If the fluid reaches the cylinder through the air filter, the engine stops abruptly. We see the Check engine light flashing on the panel.
It is very hard for inexperienced motorists to repair the engine by themselves. However, it is quite easy to know the reason of Check engine light flashing. Please remember the key rule: prevention is always better than cure!
