Those who don't know much about cars will run to the car center immediately because they are scared and anxious when the instrument panel lights up.
However, sometimes car centers trick novice drivers and recommend that they replace healthy parts, so it's good to know the cause of simple problems.
I will tell you the cause and solution when the yellow light is on in the car engine check light.
A yellow light means a danger signal, not a warning.
There is something wrong with the car right now, so you need to quickly check and have it checked.
There are many causes.
1. When the gas cap is not properly locked : When closing the gas cap, it must be closed tightly until a click is heard.
2. When refueling without turning off the ignition : When the ignition is turned on and refueling, the car sensor sends a danger signal because air flows in. Gasoline vehicles are more sensitive due to the nature of gasoline that evaporates well and is at risk of explosion.
3. Spark plug problem : Spark plugs only in gasoline cars have an ignition device that lights up a fire, but if a gap in the spark plug opens, a danger signal appears.
4. When to replace the fuel filter : Check the manual on each vehicle carefully to know when to change the fuel.
