Mitsubishi ASX Клуб

Всем доброго времени суток! Являюсь владельцем ASX около полугода. Машинка 2011 г.в.V1,8. На данный момент пробег около 71 тыс. км В принципе машинка всем устраивает. Но есть одно "но". Около месяца назад загорелась лампочка "check engine". Диагностика показала ошибку лябда-зонд 2 (стоит после катализатора). Стерли ошибку. Заправлялся на другой АЗС. Лампочка не загоралась. На 70 тыс. заменил масло ДВС и свечи. Проехал около 700 км и вдруг ни с того, ни с сего "check" загорелся вновь и спустя 300км пути погас. С чем можно связать причину такого поведения и какие действия посоветуете? Заранее всем спасибо за дельный совет и удачи на дороге!

У меня была схожая проблема на предыдущем авто, так же заправился не важным бензином. Пока не поменял фильтр тонкой очистки топлива ошибка периодически выскакивала....

Код ошибки какой ? Их там по ДК 2 около пяти штук...

А чем тема старая с ошибками неустроила

Для России:

Code No. P0137: Oxygen Sensor (rear) Circuit Low Voltage <Vehicles for Russia>


OPERATION



The sensor signal is inputted to the engine-ECU (terminal No. 40) from the oxygen sensor (rear) output terminal (terminal No. 3).
The engine-ECU (terminal No. 41) applies an offset voltage of 0.5 V to the oxygen sensor (rear) (terminal No. 4).
FUNCTION



The oxygen sensor (rear) converts the concentration of oxygen in the exhaust emission into a voltage and inputs the signal to the engine-ECU.
When the air-fuel ratio is richer than the theoretical air-fuel ratio, the oxygen sensor (rear) outputs a voltage of about 1 V. When it is leaner than the theoretical air-fuel ratio, it outputs a voltage of about 0 V.
In response to the signal, the engine-ECU controls the fuel injection amount so that the air-fuel ratio can be equivalent to the theoretical air-fuel ratio.
TROUBLE JUDGMENT


Check Conditions
Oxygen sensor (rear) offset voltage is more than 0.4 V and is less than 0.6 V.
Battery positive voltage is more than 11 V and is less than 16.5 V.
More than 3 minutes have passed since the engine starting sequence was completed.
Judgement Criterion
Oxygen sensor (rear) output voltage is less than 0.2 V for 2 seconds.
FAIL-SAFE AND BACKUP FUNCTION



None
PROBABLE CAUSES



Failed oxygen sensor (rear)
Open/short circuit or harness damage in oxygen sensor (rear) circuit or loose connector contact
Failed engine-ECU

для начала проверьте проводку датчика под днищем на предмет повреждения изоляции...

Коллеги, а если человек с английским не дружит?:) форум мне кажется на то он и форум чтобы дать по возможности совет а не отсылать лопатить ERROR LIST

Существует масса онлайн-переводчиков в интернете. Да, многие из них переводят "коряво", но уловить смысл про типовые причины возникновения кода неисправности вполне возможно.
P.S. Советов можно дать много....Проверить проводку датчика. Если изоляция сигнальных проводов повреждена и будет "коротить" на корпус авто, то можно словить P 0137.
Можно проверить опорное напряжение, которое ЭБУ двигателя выдает на датчик. Оно должно быть ~0.5 v... Сделать это можно с помощью мультиметра в подкапотном блоке предохранителей, измерив напряжение на соответствующих проводах белого большого разъема при включенном зажигании.Схемы из мануала, ссылку на который уже дали - в помощь.

Если человек не дружит с английским, не разбирается в устройстве авто, никогда не пользовался мультиметром(и не хочет этому научиться) - совет может быть один: ищите хорошего диагноста.
