do somebody ever have this problem?...

on my civic , i had a check engine, default 41. (41: Heating sensor oxygen or LAF)


we changed the o2 sensor (ordered by Honda), i reseted the ecu, but i still have this check engine!

the car roll very good, very good idle...

we think to a connector, a wire...

take it for a few runs to bed in maybe? it will take a fair few turns on the ECU to recognize the sensor from what i have found.

 

does your model have 2 sensors?? one pre cat and one in the cat
