ошибка PCM + Check Engine
 
Вложений: 2
Всем привет,
может кто сможет по графикам определить?

Это график 5 минутной поездки. За время поездки 3 раза срабатывали Check Engine + PCM error

Меня смущают скачки на графике Throttle position.. не слишком ли они высокие? по ощущениям, ошибки вылетают в моменты этих скачков на графике. это поездка в 5 минут без прогазовок и рывков, просто прогревочная езда (правда по холмистой дороге).
Есть остальные 60 графиков, которые считывает obd2, могу дополнить

Так а какая ошибка-то?

misfire по 4-5-6 цилиндрам, а иногда наоборот по 1-2-3

Хороший такой букет, похоже на проблемы соединения с DME, придется ехать к профессионалам.

Слишком много всего вылезает. Это после стирания кодов и одной поездки?
Мотор атмо или турбо?

мотор турбо

с ошибками я не понимаю логики, что-то стирается сканером, что-то остается
сканер самый простой.. поэтому и задал вопрос про piwis с соседней ветке

а вот коды ошибок, которые вылетали при другой поездке:

Такое ощущение что протерся жгут на эбу двигателя.
Для начала посмотреть на сколько реальны показания ДТОЖ и ДМРВ, далее
1. Проверить проводку ДВС(заодно прозвонить подогрев задней лямбды, есть ошибка по подогреву, которая должна зажигать чек)
2. Опрессовать впуск
3. Проверить давление топлива

с ОЖ все ок, греется до "стрелка на середину" и там остается.. график датчика ОЖ это подтверждает, никаких скачков и тд. t 86-87 c
ДМРВ меняли на новый.. не исправило. При этом я пробовал его отключать вообще, не помогло тоже
проводку ДВС осматривали в двух сервисах .. насколько компетентно, я не могу сказать.. т.е. эта версия не исключается

по поводу впуска, была версия что дроссель плохой, поставили новый - не исправило
опрессовывать впуск в наших краях не знают/не умеют
я хочу попробовать способ с баллончиком (пшикать и слушать обороты) как думаете?
с другой стороны, если бы был такой сильный подсос воздуха, вылетали бы другие ошибки (?)..
давление топлива не проверяли

интересно что в жару все ошибки уходят и проявляться начинает при понижении до 24-25 и ниже

DC 25.09.2021 12:51

по поводу давления топлива
с динамикой у авто полный порядок, разгон и тд - все как обычно

и еще и симптомов, на холодную, при прогреве авто - плавают обороты, иногда сильно
после прогрева стабилизируется

avolkov 25.09.2021 14:00

блин, такой ворох ошибок, что-то явно с проводкой или разъемом. Посмотрите еще раз внимательно, неторопясь. У меня когда-то давно мышь или крыса прикусила одну и кос и долго не могли понять что с машиной.

Можно еще вот здесь тему создать, народу там побольше...

а бывает в природе визуальная схема проводки? слишком там все плотно, нужно знать где именно искать :confused:

на реалисте пробовал темы создавать, решение никто не подсказал

avolkov 25.09.2021 14:34

Можно на ютубе посмотреть как двигатели снимают, вопрос проводки должен быть неплохо отражён.

Например
