Спасибо, большое А то у меня с этими ошибками уже нервный тик скоро начнется... Я Кстати её вчера вечером тоже скинул посмотрим какая следующая )))

Сейчас на работу ехал опять 170я вылезла, в общем вернусь и буду его починять....
А вообще вдруг не с того, не с сего полезли ошибки связанные с лямбдами, может я где заправился каким нить г......ом? Я просто пытаюсь понять в чем причина?

Ну вот пришло время побеждать проблему, расход действительно увеличился, но выявить истинные причины тяжело то ли виноваты муды толи лямбды.
Дорогие друзья, помогите определиться с чего начинать, какую лямбду или лямбды менять, понимаю что вопрос уже много раз обсуждался но покурив поиск так и не понял какая конкретно виновата, если не сложно можно прямо на картинке ткнуть меня носом? или может дело не только в лямбдах, ошибки как и прежде 125я и 170я.
Зато чудесным образом пропала ошибка ЕГРа

Всем Привет ! Р0173- Что за ошибка? Чек горит на ходу.

P0173 Утечка топлива из топливной системы блока цилиндров №2

а вот при чем тут 173 мне вообще не понятно
Дорогие мои, гуру, поможите мне пожалуйста глупому

вот каой из этих? или я так понял могут быть два в первом банке? тогда какой из этих банков первый

173 часто загорается при наевшемся лямбдазонде или хреновом бензине, так же может загореться при трещине в выпускном коллекторе. Первая банка- это передний правый, померить надо датчики и все встанет на свои места

В смысле утечка топлива??? Сделал диагностику движка, только 173 ошибку и выдает. Ее удалили, на следующий день опять все по новой. В сервисе грешат на бензин и фильтр, а в большей степени на инжектора (говорят необходима ультрозвуковая чистка)думаю лажа(развод). Честно я этим методам не доверяю, да и сервисам тоже, больше все сам. Если лямда выходит из строя скан выдаст неполадку (есть определенный код)? Движок ровно работает,бывает перебои из-за бензы скорее всего. Как понимать фразу наевшийся лямд- это с чем едят???

Наелась, значит вышла из строя. Прозвоните лямбды. При наличии нормального сканера и толкового диагноста делается на раз, если нет перечисленного, то померить напряжение хотя бы, плавать не должно.
ЗЫ Утечка топлива- кривой перевод на русский. Вот оригинал

Спасибо Снуперу)))

Так если скан не показал ничего, как быть? А чек горит практически постоянно, только периодически гаснет. На счет напряжения, оно должно быть одинаковым на оба лямда? Двигу звпускать?

как это скан ничего не показал и чек горит? Нужно выбросить такой скан.... или диагноста!
двиг естественно запускать.

Сканов других у нас в городе нет. Кроме 173 ничего не выдает. Сам думал изначально на лямд, но скан ввел в заблуждение, собираюсь фильтр новый брать. Посмотрим что измениться.

Ошибка Р0173 говорит о нарушении топливно-воздушной смеси в правой голове(цилиндры 2,4,6)
Что нужно делать я давал выше. Что бы не делать лишней работы, нужно просто померить давление в топливной системе и все станет ясно, менять ли фильтр-насос, либо искать дальше.

О! Только сейчас заметил, что мотор, да и машина другие))) Но смысл тот же, за исключением головы

On Federal vehicles, DTC P0170 applies to fuel trim malfunction on either bank. On California vehicles, DTC P0170 applies to fuel trim malfunction on bank 1 (cylinders No. 1, 3, and 5).

У Whitewind 170 ошибка, как понять, машина федеральная или Калифорнийская?
В первом случае менять обе лямбды, во втором - только на нечетной башке.
Или у федеральных всего одна лямбда уже после "штанов" и ее надо заменить.

125 ошибка судя по всему - тоже из-за лямбды. 125 - основная ошибка и 170 - чтото типа расшифровки ее?

125 не из-за лямбды.

On 3.5L engine, reading should be 18-44 at idle and 58-98 at 2500 RPM. If reading is within specification, go to next step. If reading is not within specification, replace VAF sensor, then go to step 13 .
12Check for fuel injector leakage. Check fuel for contamination. If problem exists, repair as necessary, then go to next step. If problem does not exist, replace PCM, then go to next step.
13Using scan tool, clear DTCs. Test drive vehicle following OBD-II drive cycle fuel trim monitor pattern. See OBD-II DRIVE CYCLES under VERIFYING REPAIRS in SELF-DIAGNOSTICS - INTRODUCTION article. Check for DTCs. Confirm DTC does not reset. See VERIFYING REPAIRS in SELF-DIAGNOSTICS - INTRODUCTION article.

NOTE: Federal vehicles have one front HO2S located in exhaust pipe upstream of catalytic converter. California vehicles have 2 front HO2S, one located upstream of left bank front catalytic converter and the other located upstream of right bank front catalytic converter.

Check front Heated Oxygen Sensor(s) (HO2S). See SENSORS under ENGINE SENSORS & SWITCHES in SYSTEM & COMPONENT TESTING article. If problem exists, replace front HO2S, then go to step 7 . If problem does not exist, go to next step.
