Этот датчик — скрытая причина плохой работы двигателя

Before starting the engine, the control unit performs several important procedures that most car owners aren't even aware of. A split second before starting, the ECU measures barometric pressure and uses this parameter to calculate the initial mixture ratio. If the value is recorded incorrectly, the engine will have difficulty starting, run rough, and experience stalls and excessive fuel consumption. In this video, I explain in detail what the ECU does when the ignition is turned on, how it evaluates barometric pressure, why some systems use the MAP sensor, and what malfunctions lead to incorrect mixture ratio calculations. I show real-world examples from diagnostics and explain what values ​​are considered normal. This video will be useful for those involved in diagnostics, repairs, and anyone who wants to better understand their vehicle. 🤝Thanks to our sponsors for supporting the channel: Mizantrop, Andrey Artemyev, Evgen Shramenko, Vitaliy Bashinskiy, Vladimir Murashkevich, Evgenii Shvets, Andrii Kozub (Electric Dobropillay), Alex Nemez, Denys Vasylenko, and Oleksandr Goncharenko! 🤝Support the channel👉 https://sobe.ru/na/moylacetti ⚡Or become a channel sponsor and you'll gain access to exclusive bonuses.
