For many driver drivers it is a pleasure and always a car trip is welcome. However, there are things that can ruin the good mood and among them there are the aspect of warning witnesses on the vehicle. Depending on their color, a larger or smaller problem is indicated, the red ones feel like a serious problem that requires immediate intervention. Orange or yellow witnesses indicate a malfunction that must be studied as quickly as possible and green, blue or white indicate the use of some vehicle functions.

What does the control engine mean? A control engine witness can indicate a series of failures and therefore gives the creation to any driver.
Why does the control engine appear? It appears in the form of a symbol or a text and is a witness in the orange category, therefore it does not indicate a serious problem, but reports the need to verify the system.
The witness of the control engine frightens, in particular, the beginner drivers of his name.
What do you have to do when the control engine witness appears?
Checking the engine does not necessarily indicate a serious problem, but it is very important to try to discover the cause, otherwise the risk of a serious defect increases. Sometimes, the control engine witness is provided with other witnesses, so it is easier to understand where the malfunction comes from. Otherwise, you can check some aspects to understand it. If the vehicle in question is what you are currently driving, then you certainly know how the engine sounds in the optimal parameters. Therefore, it is advisable to listen to the sound of the rolling engine and ranks. The hood opens and checks the following: possible loss of pipes/connections, the electrical and electric connections of the battery, the covers of the ship to be closed correctly and at the same time, check the joja indicating the level of the oil. If after checking these possible causes you have not discovered the source of the problem, you need to go to a service or use an OBD scanner (if you own) to find out what the error is.
2. Check the engine: causes for which the control engine is on
Why does the engine control lights up? The appearance of the witness of the car control engine is generated by multiple reasons. The most common ignition situations of the control engine witness are as follows:
- Low battery voltage, the battery does not charge or work defective;
- The sheets or candles do not work and their wear and use inappropriate fuel combustion;
- Forests of the alternator who can cause start -up problems;
- Clogging of the EGR valve that guarantees the recirculation of the exhaust gases;
- Defect of the air flow sensor that measures the amount of air necessary to correctly burn the fuel;
- Lambda probe defects, component responsible for optimizing the fuel combustion process in order to have low pollution emissions;
- The tank register is not strictly correct or missing. Its role is to seal the supply system, so that, distinguishing it, there is the risk of evaporation of fuel and low pressure in the tank.
3. How can you find out what problem the signs of the control engine witnesses?
To discover a control engine error, the vehicle is required. This is done through an OBD scanner that connects to the OBD II connector that transmits the data on different sensors in real time. Therefore, if a sensor works defective or is inactive, it will be a specific error code and therefore the problem can be identified. Because of this scanner the market of Car sales It is safer because you can easily check if the vehicle hides certain errors.
OBD II is the standard of diagnosis of most common cars, there is also OBD I which is an older interface, used in the past. Both play the same role, only that OBD is a more recent version provides better precision information. It should be noted that OBD II exists in two variants of connectors: type A, dedicated to vehicles with 12 V and type B input voltage, dedicated to vehicles with an input voltage at 24 V. The jacks of the two types are different in order not to cause damage to the hardware system, but if you want to buy an OBD scanner, it is advisable to pay attention to which type of connector combines your car.
If the witness’s warning is intermittent, it means that a problem is reported that a specialist requires. In general, this type signal indicates a cylinder or induction coil In the situation given it is good to call a specialist who can tell you if it is right to travel to the service with the vehicle or a platform.
Therefore, it is important not to ignore the signals transmitted through the witnesses even if at first glance it does not indicate serious problems. If we do not intervene in time, minor problems can be transformed into serious failures which, in addition to the wasted time and the maintenance of the vehicle, can also involve high repair costs.
