Nemáte prosím zkušenost s touto chybou? Dá se z toho logu říci, zda je problém v té lambda sondě?
Před rokem mi ještě na záruku měnili katalyzátor, od té doby byl klid...

1 lambda bude KO, nebo poškozená kabeláž. V každém případě to zkontroluj, nebo vyměň lambdu. Špatná přední lambda ti může zničit mimo jiné katalyzátor.

Děkuji moc za reakci. Tak to bych nerad nechal zničit rok starý katalyzátor... Je "Bank 1 Sensor 1" ta horní sonda? V dílech označované jako ČIDLO - HEGO 1886204? Je to vyměnitelné bez toho speciálního klíče?

Takto vypadala moje horní (přední) lambda po vymontování. Dá se z té barvy něco přímo usoudit?
Nikde nemohu najít zapojení pěti drátové lambdy s těmito barvami:
1 - červená
2 - žlutá
3 - bílá
4 - šedá
5 -
6 - černá

Mezi šedou a bílou je 3,4 Ohmu, to si myslím, že je vyhřívání?
Na čem měřit signál černá - žlutá?
Je po výměně nutné resetovat PCM?

Aly motor?

Ford Focus MK3, 1.0 EcoBoost 92 kW

Vracím se ještě k té barvě mé přední lambdy před výměnou.
Narazil jsem na článek s obrázky:
http://autoprollc.com/wp-content/upload ... -guide.pdf

Té oranžové je asi nejblíže tento popis:
"Shiny, dark grey deposits.
Cause: Contamination due to use of leaded fuel.
Lead attacks the platinum which is present both
on the sensor element and in the catalyst.
Solution: Remove the leaded fuel from the
vehicle, and refill with lead-free fuel.
Replace the sensor."

Je asi blbost aby jsi tankoval olovnaté palivo. Dneska jsem měl lambdu taky vytaženou a byla celá černá, jak ta tvá u závitu.

Také si myslím, že jsem olovnatý benzín netankoval...
Dával jsem to sem, zda nemá někdo zkušenost s podobnou barvou.

Neviem či ťa to upokojí ale ja mám taký odtieň za turbom. Ecoboost 2.0 177kW

Barva je podobná. Já nevím, já jsem lambdu (možná tedy zbytečně) preventivně vyměnil, nechtěl bych aby odešel zase katalyzátor. Už mi ho jednou na záruku měnili. Chyba se mi po výměně lambdy znovu neukázala. Je ale pravda, že jsem kamarádovi stejnou chybu na stejném autě také už jednou mazal a od té doby se mu neprojevila a nic neměnil.
