Eroare sonda lambda dupa ce am schimbat-o P0130 si P0135

Corsa c 1.2 z12xe din 2003. Am schimbat sonda lambda cu una noua, insa erorile s-au pastrat. Atasez cele 4 imagini de pe tester. Ceva idei?
Daca sterg erorile, dupa cativa km apar din nou.

Nu.... Masina suna ok, trage ok.
Vroiam sa rezolv problema cu sonda lambda intai.

Fa o diagnoza completa sa poti vedea parametrii in timp real. De multe ori codurile de eroare nu te ajuta pana nu vezi cum mesteca motorul. Vad ca esti din Iasi. Ia legatura cu Dan Cuciureanu de pe forum. Cred ca te poate ajuta. Mie imi suna a ECU defect sau cablaj intrerupt de la mufa la ECU.
Bafta.

2 sau 1?

2 e abia schimbata.

Ar fi bine sa rezolvi mai intai cu distributia...daca e sarita de la punct, se mai intampla la cele pe lant, din cauza patinelor, automat ai si un amestec incorect, lucru vazut si alertat de Prima sonda lambda. La inlocuire, stiu ca sunt cam pretentioase, nu se innadesc, nici nu se prea lipesc, ci se prind cu niste capse...

Salut , problema ta este un contact imperfect aleatoriu (Circuit Open) . Este destul de dificil sa gasesti unde este sectionat cablajul sau oxidata mufa de conexiuni pentru ca nu ai ce sa masori problema fiind din cand in cand..Daca la inlocuire ai folosit lambda universala la care se lipesc firele 90 % acolo este problema. Neaparat se cositoresc conexiunile.... cu aer cald nu cu pistol de lipit.
Daca totul e ok curata mufele ECU. Poate fi o problema si de ECU totusi...
Preferabil este o sonda lambda SH de origine decat una universala. Cele universale de obicei sunt mai lente in raspuns si nu rezista decat vreo 10 000 km in cel mai bun caz.

Sa inteleg ca ai un op-com...cu contactul pus, sterge erorile, du-te apoi la parametrii, si vezi la tensiune sonda lambda bank 1 (prima) si urmareste tensiunea ( cea in mV). Daca totuk merge corect, ea trebuie sa oscileze. Daca ceva este in neregula, ori scade si apare eroare, ori creste si apare eroarea. In cazul tau, cred ca va fi o tensiune mica... Dupa cum am mai spus, in putine cazuri sonda chiar e defecta. Ea ,,ii spune'' calculatorului ce corectie de benzina sa faca pentru ca amestecul carburant sa fie cat mai bun. Ea citeste cantitatea de oxigen din aerul evacuat, transmite informatia catre ECU, iar acesta modifica amestecul. Daca sonda transmite de mai multe ori informatii, ECU modifica amestecul, dar nu se schimba nimic in bine ( de exemplu fisura in admisie sau evacuare, ardere incompleta s.a.m.d. ) ECU da eroare ca sonda lambda este defecta sau valorile nu sunt cele corecte, si nu mai tine cont de ea.

Si din cate stiu, Z12XE este pe lant....
