Высокое давление во впускном коллекторе? Не меняй датчик, пока не проверишь это

In this video, we'll explore why intake manifold pressure is elevated at idle and why standard air leak detection won't reveal anything. Using a visual experiment with graphs, I'll show how a tired battery, alternator load, and other non-obvious factors can increase intake manifold pressure and increase fuel consumption. 🤝Thanks to our channel sponsors for supporting the channel: Mizantrop, Anatoly Krizhanovsky, Evgeny Shramenko, Vitaliy Bashinsky, Vladimir Murashkevich, Andrii Kozub (Electric Dobropillay), Evgeny Shvets, Oleksandr Goncharenko, Denys Dubinenko, Oleksiy Kolosov, Sasha Rubchenko, and Oleksandr Zabolotny! 0:00 — Problem demonstration: elevated intake manifold pressure (almost 40 kPa) immediately after starting the engine. 0:48 — An unexpected solution: checking the battery condition and charge due to the starter running. 1:08 — Charging the battery and repeating a cold test start. 1:51 — Successful result: normalization of intake manifold pressure after charging the battery. 2:01 — Visual experiment: how turning on the heater, headlights, and heater immediately increases pressure. 3:01 — Theory: why intake manifold pressure reflects the actual engine load. 3:17 — The connection between the alternator and the engine: how a discharged battery increases current and hinders rotor rotation. 4:14 — What else affects intake parameters and why the air leak myth is misleading. 5:05 — Practical diagnostic tip: removing the alternator belt to check the attachments. 5:28 — What to check in the engine if the pressure has not dropped with the alternator belt removed. 5:46 — The video's main takeaway: high pressure is just a symptom, like a high fever in humans. 6:20 — Analysis of common situations: causes of high pressure immediately after starting (battery and fuel injectors). 7:03 — Why pressure can be consistently above 40 kPa (timing phases). 7:32 — The effect of the oxygen sensor on pressure and recommendations for checking the leakage current. ⭐Contact the author👉 https://moylacetti.ru/obratnaya-svyaz/
