CHECK ENGINE
Many of us have experienced such a problem as turning on the check engine icon.⠀ 5 most common reasons: ⠀ ⠀ ➊ Oxygen sensor (lambda probe)⠀ ⠀ It is part of the exhaust aftertreatment system that controls how much oxygen is not burned in the engine's combustion chamber and helps control the car's fuel consumption. Most cars have 2 to 4 sensors. ⠀ ➋ Fuel filler cap⠀ ⠀ If the car has not lost power and there are no audible signs of engine damage, then check the gas tank for leaks. The cover may be cracked or not tight enough. ⠀ ⠀ ➌ Exhaust catalytic converter⠀ ⠀ If it has become unusable, you will notice this not only when the Check engine appears, but also long before that, when the car's power drops by 2 times. ⠀ ➍ Mass Air Flow Sensor⠀ ⠀ A faulty sensor increases fuel consumption, increases CO2 levels in the exhaust gas, and reduces engine power and ride quality. In cold weather, the car does not start well. ⠀ ➎ Spark plugs⠀ ⠀ Faulty spark plugs often have a lack of spark or an incorrect spark interval, which affects the operation of the engine. ⠀
