P052e00 audi ошибка

• Плохой регулирующий клапан PCV
• Неисправный клапан PCV
• Неисправен датчик давления в картере
• Обрыв или короткое замыкание в проводке регулирующего клапана PCV / датчика давления в картере
• Неисправность PCM или ошибка программирования PCM

Пример датчика давления в картере:

Каковы некоторые шаги по устранению неполадок P052E?

По моему опыту, при диагностике кода P052E потребуются ручной вакуумметр, диагностический сканер, цифровой вольт / омметр (DVOM) и надежный источник информации о транспортном средстве.

Перед диагностированием любых кодов недостаточного давления в картере / PCV необходимо выполнить ручное испытание вакуумного давления. Если двигатель не создает достаточного вакуума, его необходимо отремонтировать, прежде чем приступить к диагностике. Чтобы провести ручную проверку давления вакуума, отсоедините вакуумный шланг PCV и подсоедините к нему манометр. Ваш информационный ресурс о транспортном средстве должен содержать спецификации относительно минимального вакуума в двигателе.

Проверьте все шланги PCV на наличие трещин или поломок и при необходимости отремонтируйте. Треснувшие или сломанные вакуумные шланги PCV могут способствовать условиям, которые привели к хранению P052E.

Если двигатель находится в хорошем рабочем состоянии и нет утечек вакуума, продолжите визуальный осмотр всей проводки и разъемов регулирующего клапана PCV и датчика давления в картере. Сделайте ремонт по мере необходимости. Затем я подключил сканер к диагностическому порту автомобиля и получил все сохраненные коды и данные о стоп-кадре. Запись этой информации может помочь вам по мере развития вашего диагноза. После этого очистите коды и проведите тест-драйв автомобиля, чтобы убедиться, что код сброшен.

Используйте свой информационный ресурс о транспортном средстве, чтобы получить виды разъемов, электрические схемы, схемы контактов разъемов, процедуры тестирования компонентов и спецификации. Вся эта информация потребуется для продолжения диагностики.

   PCV Regulator Valve Performance*P052E00
   

   So I recently replaced my PCV and everything went well. But after a long drive yesterday I’m getting a rough idle. Plugged in the obdeleven and received this error code «PCV Regulator Valve Performance*P052E00». Does anyone know what else would of set this off? I bought the PCV from Audi and I’m not losing any oil or coolant.

   I had the same exact code on a fairly new PCV. Took it back to the garage that replaced it for me. They actually tested the PCV and it turned out to still be functional. Reinstalled it and took it for a test drive. Same code came back. It turned out to be a the solenoid coming off the PCV that was stuck open and air flowing all the time. It’s called the crankcase breather pipe, part number 06E103207AP. I only got it back 3 days ago and so far no code.

   I’ll check it out. I didn’t replace this part. Thank you for this info!

   This is a common issue. The solenoid is causing this fault. You most likely needed the breather as well though. They all fail.

   Please confirm the part(s) you are referring to — 06E103207AP is a breather hose, it has a inline check valve but no solenoid (by definition a solenoid is an electromechanical part) so it is not clear what part you replaced. Did the check valve fail? Not trying to be picky just want to make sure in case I need the same item. Like most PCV items VAG charges a fortune for a little bit of plastic so I want to get the right part. Thanks!

   That was the part listed on my invoice from the garage. And that’s how it was explained to me. I guess it’s that check valve that failed. Sorry for the confusion. Maybe they manually activated a solenoid to test the check valve?

   Okay, I am in this situation right now with Audi and trying to get this code P052E00 addressed. I had my PCV replaced about 17,000 miles ago but this code has popped up since with the associated symptoms (oil consumption, strong vacuum when taking oil cap off etc.)

   That being said the part number that is being listed on this thread and the one that Audi is telling me is needed in addition to a new PCV is 06E103207AP. However, when I search this part on Audi Parts, it tells me that «This Part does not fit your car»;

   https://parts.audidominion.com/p/Aud…e103207ap.html

   Any insight into this? When I search FCP and ECS they also both state that this part will not fit my car…

   https://www.fcpeuro.com/products/vw-…vw-06e103207ap

   https://www.ecstuning.com/b-genuine-…e/06e103207ap/

   Bottom line, is this a valid part for a 2017 SQ5?

    There were two PCV versions of I remember correctly, technically both would fit, but the later one may require a tune revision in order for it to function correctly and not give the error message. Could also simply have been a bad part too on the initial replacement.

    The other parts I can’t speak to, but might be worth looking at since it could be the issue with why this one went bad so fast.

    I have heard about needing to tune or update the ECU for the new PCV. in fact there�s an updated part number for the PCV that has come out since I had it replaced back in July of 2020. So I�ll make sure to bring that up.

    What I am asking about the parts I listed above is wether or not that part actually fits on the SQ5. When I pull it up on the Audi parts website it says it doesn�t. My dealer is insisting it does fit and that it needs to be replaced

    Don’t worry what the Audi parts website says — it’s usually right but not 100%. What you need to be doing is doing the search with your VIN. Don’t waste your time worrying about stuff like will this or that fit my car and which version do I need, just buy the part using your VIN instead cause that’s 100%. I see so many people here making this basic mistake.

    One example of this is www.audiusaparts.com and you will notice when you checkout you have to provide your VIN.

    Same thing is happening to me in my 2013 A6. Just replaced my pcv, still getting a soft code. I’m going to replace the breather tube and see what happens.

    I had bad oil consumption & was blowing blue clouds of smoke from it. The pcv swap fixed the blue clouds, but I’m still having oil consumption.

    Thinking about grabbing the 65$ tube from fcp… If it breaks early at least it is warrantied for life.

    Since I had the crankcase breather pipe, 06E103207AP, replaced back in December, everything seems to be running smoothly. My Q5 was alerting me for a quart of oil every 2,000 miles before. Now, no more soft code and oil consumption is greatly reduced.

    Seeking a little guidance from those in the know…So I’ve been having the usual signs of a bad PCV valve (strong suction on the back of the valve, oil cap difficult to open with engine running etc.) so I went ahead and replaced the cap with the Dorman unit that everyone’s been using. The old cap had a big tear in the diaphragm, so I got great results from the new unit. However, I’m still getting a bit of suction at the back of the new valve, but the oil cap is much easier to open now (I’ve been told that some suction is normal).
    Drivability is much improved, but I’m still getting a slightly rough idle and the car feels a bit sluggish on move off. I’m wondering if I needed to replace the entire PCV valve and not just the top. Is there any test that I can do to tell? Also, I hear much talk about the crankcase breather pipe with the check valve being stuck open, are these symptoms of that? Can I test that also?
    Any help is greatly appreciated.

    Which engine do you have? When you describe «strong suction on the back of the valve» and replacing «just the top» it makes me think you have a 2.0T?

    My bad, yes it’s the 2.0T (2011)
    I’m just trying to do some diagnosis of my own, unfortunately there aren’t that many «reputable» shops here that are versed in Euro’s (IMO)

    Just an update on my issues…

    My PCV Code has gone away since replacing the Breather tube that connects the PCV to the Supercharger.

    Still burning oil on deceleration… suspect exhaust valve stem seal failure.

    Question, the breather hose that you mention being the issue, is replacing that part still require taking the supercharger off?

    85% of the cost to repair the Breather Tube/PCV is in labor costs. The parts are relatively negligible in cost once you factor in what your already spending on just the labor. I had the work done at Audi under warranty and they would have hit me for 5.5 hours of labor to do the PCV, which essentially the same amount of time it would be to do just the Breather tube. Maybe knock .5 off the total labor time.

    I think parts all in was around $400.00 and that’s with buying all new gaskets and the injector «Grommet» kits that cost an arm and a leg etc..

    Agreed, if you dig into the motor far enough to replace the breather tube, then you might as well go the extra step to replace the PCV as well, especially since they are known to fail frequently. It’s not fun to dig into the motor a second time for an item that could have been replaced while you were in there the first time. Speaking of… perhaps look into replacing the thermostat and water pump if you’re gonna be doing the PCV. They’re also pretty much in the same spot and you’ll save a ton on labor if you do it now vs waiting for them to fail later.

    Though if budget is really tight, yes, you could technically probably fix your issue with just the breather tube and leave everything else alone.

    If you are going to go in there, definitely replace the whole PCV and the hose. Waste of time and effort to take all that crap off and not just replace the whole deal. It could be that hose, or it could be the entire PCV, that code could be either.

    How do u access the long size/hose of the crank case breather tube

    ---

Код ошибки P0052 звучит как «высокий уровень сигнала в цепи управления нагревателем датчика кислорода (Банк 2, Датчик 1)». Часто, в программах, работающих со сканером OBD-2, название может иметь английское написание «HO2S Heater Oxygen Sensor Control Circuit High (Bank 2, Sensor 1)».

Этот диагностический код неисправности (DTC) является общим кодом силового агрегата. Ошибка P0052 считается общим кодом, поскольку применяется ко всем маркам и моделям транспортных средств. Хотя конкретные этапы ремонта могут несколько отличаться в зависимости от модели.

В автомобилях для определения содержания кислорода в выхлопной системе до и после каталитических нейтрализаторов используются подогреваемые кислородные датчики (HO₂S). Они используют обратную связь для регулировки топливной системы. Чтобы поддерживать оптимальное соотношение воздушно-топливной смеси 14,7:1.

В кислородных датчиках используется цепь нагрева датчика для более быстрой работы обратной связи с модулем управления. Датчик кислорода может использовать три или четыре провода в зависимости от автомобиля.

Два обычно используются для обратной связи с модулем управления трансмиссией (PCM). А другие провода предназначены для нагревателя и питания нагретой цепи. Трехпроводные датчики обычно заземляются через выхлопную систему. А четырехпроводные имеют отдельный провод заземления.

Код P0052 относится к датчику перед каталитическим нейтрализатором Банк 2, который находится на стороне двигателя, где нет цилиндра №1. Ошибка означает, что проблема с нагревательным элементом датчика HO₂S не устранена. Этот код срабатывает, когда в цепи нагрева датчика кислорода обнаружен высокий уровень сигнала.

Симптомы неисправности

Основным симптомом появления ошибки P0052 для водителя является подсветка MIL (индикатор неисправности). Также его называют Check engine или просто «горит чек».

Также они могут проявляться как:

1. Загорится контрольная лампа «Check engine» на панели управления (код будет записан в память ECM как неисправность).
2. В некоторых случаях, модуль управления двигателем (ECM) может перевести автомобиль в аварийный режим работы.
3. Иногда симптомы могут отсутствовать, несмотря на сохраненный код неисправности.

При появлении кода неисправности P0052, автомобиль может продолжить движение, но проблему необходимо устранить как можно скорее. Чтобы предотвратить потенциальные проблемы, такие как отказ контура датчика и повышенный расход топлива. При долгом игнорировании проблемы, возможна неустойчивая работа двигателя, а также повреждение других компонентов.

Причины возникновения ошибки

Код P0052 может означать, что произошла одна или несколько следующих проблем:

• Обрыв провода питания, заземления или цепи нагревателя датчика O₂.
• Неисправный нагреватель датчика O₂.
• Повреждение или износ разъемов, идущих к датчику.
• Иногда причиной является неисправный модуль PCM.

Коды высокого входного сигнала цепи иногда являются результатом низкого напряжения батареи. А также плохих соединений между электрическими разъемами или ранее отремонтированной проводки. Также не исключена коррозия электрических разъемов.

Как устранить или сбросить код неисправности P0052

Некоторые предлагаемые шаги для устранения неполадок и исправления кода ошибки P0052:

1. Очистите коды ошибок с памяти компьютера автомобиля.
2. Проведите тест-драйва автомобиля, чтобы выяснить, появляется ли код P0052 снова.
3. Выполните визуальный осмотр и при необходимости отремонтируйте или замените поврежденные электрические провода.
4. Проверьте заземление, при необходимости устраните проблему.
5. В случае проблемы с PCM, перепрограммируйте или замените модуль управления двигателем.

Диагностика и решение проблем

Неисправность P0052 может быть вызвана только цепью нагревателя кислородного датчика или самим датчиком. Диагностику обычно начинают с проверки проводки датчика. Обычно датчик кислорода с подогревом идет с четырьмя проводами.

Два провода идут прямо к цепи нагревателя, а два других для питания и заземления датчика. Вам может понадобиться электрическая схема вашего автомобиля. Чтобы быть уверенным, что вы проверяете правильный набор проводов.

Проверка проводки

Проверьте цепь нагревателя с помощью цифрового мультиметра или вольтомметра. Сверьтесь со схемой проводки автомобиля, чтобы определить точные контакты разъема, на котором установлено заземление.

Показания должны быть близки к напряжению батареи. Если это не так, то скорее всего существует проблема с питанием датчика.

Также необходимо проверить заземление. Для этого необходимо положительную клемму аккумулятора соединить с красным проводом мультиметра. А черный провод к заземлению, чтобы проверить заземление цепи. Результат должен быть 12 В, если нет, то это указывает на проблему заземления на датчике.

Проверка датчика

Если питание и заземление в порядке, то следующий вариант проверить нагревательный элемент датчика. Чтобы определить, есть ли у него обрыв цепи или высокое сопротивление.

Установите вольтомметр на шкале Ом, проверьте сопротивление цепи нагревателя, используя электрическую схему в качестве справки.

Убедитесь, что вы отключили кислородный датчик O₂. Цепь нагревателя внутри датчика должна иметь небольшое сопротивление. Превышение предельного значения указывает на обрыв в нагревательной части. Поэтому датчик кислорода придется заменить.
