Salutari

 

Poate cineva sa ma ajute cu ceva sugestii, de unde as putea sa incep sa caut hiba sau hibele.

Masina merge neregulat, iar la rece face ceva zgomote ciudate la motor?

Pe tester apar urmatoarele:

CB/71 - Oxygen sensor control, bank 2, control limit, mixture limit rich

CA/71 - Oxygen sensor control, bank 1, control limit, mixture limit rich

F2/B2 - Misfire, cylinder 5, misfiring during warm up, worsening emissions (Misfire CARB_B1)

F0/B2 - Misfire, cylinder 3, misfiring during warm up, worsening emissions (Misfire CARB_B1)

F1/B2 - Misfire, cylinder 4, misfiring during warm up, worsening emissions (Misfire CARB_B1)

E3/71 - Oxygen sensor controller, bank 1, deviation too great, deviation rich

E4/71 - Oxygen sensor controller, bank 2, deviation too great, deviation rich

Shadow-memory:

5A/12 - Exhaust temperature before catalyst, bank 1, signal line, short circuit to negative

5B/12 - Exhaust temperature before catalyst, bank 2, signal line, short circuit to negative

5D/12 - Exhaust temperature after catalyst, bank 2, signal line, short circuit to negative

CB/71 - Oxygen sensor control, bank 2, control limit, mixture limit rich

CA/71 - Oxygen sensor control, bank 1, control limit, mixture limit rich

F2/B2 - Misfire, cylinder 5, misfiring during warm up, worsening emissions (Misfire CARB_B1)

F0/B2 - Misfire, cylinder 3, misfiring during warm up, worsening emissions (Misfire CARB_B1)

F1/B2 - Misfire, cylinder 4, misfiring during warm up, worsening emissions (Misfire CARB_B1)

E3/71 - Oxygen sensor controller, bank 1, deviation too great, deviation rich

E4/71 - Oxygen sensor controller, bank 2, deviation too great, deviation rich

 

Errors after clear:

 

no errorsShadow-memory:

5A/12 - Exhaust temperature before catalyst, bank 1, signal line, short circuit to negative

5B/12 - Exhaust temperature before catalyst, bank 2, signal line, short circuit to negative

5D/12 - Exhaust temperature after catalyst, bank 2, signal line, short circuit to negative

 

 

Multumesc anticipat.
