5 Important Malfunction Indicator Light and Meaning

There are dozens of different warning lights in the instrument panel of our vehicles. These lamps communicate with sensors located in different parts of the vehicle and illuminate to warn the driver when there is a different situation than specified by the manufacturers. We list five of these Malfunction Indicator Lights that are very important and that are of great importance to the system.

On the other hand, there are some warning lamps that we don’t include in this list, and they will often burn. Lamps such as wiper water warning lamp, seat belt light lamp, lighting lamps, handbrake warning lamp and fuel warning light can go on frequently, but these are not directly related to the driving system. Therefore, we do not include these lamps in the list.

1.Engine Malfunction Light (Check Engine Light)

This warning lamp is the most important fault lamp indicating a failure in the motor. However, it does not indicate a single fault and this lamp may go on as a result of many different faults.

This may light up in case of incorrect or non-standard fuel intake, oxygen sensor failure, air flow sensor failure, EGR valve fault, and catalytic converter failure problems. In addition, it may be responsible for the lighting of this lamps even if the fuel tank cap remains loose.

3.Temperature Warning Light

The overheat warning lamp indicates a problem with the engine cooling system. Internal combustion engines produce very high heat, due to the principle of ignition and the parts that are subject to friction. The engine cooling system is activated after a certain temperature and cools the engine to the desired temperature. If the coolant with a significant place in this system is missing, the lamp may show up.

Generally, when a decrease in engine oil or a drop in oil pressure occurs, the light may go on, in some cases, also occur due to a prolonged period of service. Because of the oil that loses its lubrication feature, both the oil pump is forced and the smooth lubrication is not ensured where the oil is needed and the friction increases. Therefore, the engine oil warning lamp may illuminate.
