Hi! I hope you can help me solve the following problem:
Description of the problem:
The user reports failures and shakes in his Honda Civic EXS 2009 AT, mainly between 80 and 100 km/h. The problem is also noticeable in the exhaust pipe and, sometimes, it is difficult to start the vehicle. The scanner returns a fault code related to the oxygen sensor (O2S).
Repairs made:
Replacement of ignition coils and starter spark plugs.
Replacing the O2B1S1 oxygen sensor.
Ask:
Despite the repairs made, the problem persists. What other causes could be generating the failures and shakes?

is o2 sensor OE? Denso or NTK? Hondas no like aftermarket electronics
