I just bought this 98 Honda Civic it has a DC header on it. I have two O2 sensors and I can keep the check engine light off. Is there any way to bypass this so I dont get the light to come back on. HELP PLEASE

 

no, you NEED an oxygen sensor
If the header doesnt have a bung (which really, really surprises me) you need to get one put in it

Sure. Pull the O2 sensor and watch as your gas mileage drops... then pull the CEL bulb out.

Ok... if you actually do this you should probably be slapped.

Perhaps you should try, oh I dunno... checking the code that the CEL is throwing and getting it fixed?

 

drill a hole and weld a bung for your o2 sensor. or have someone else do it for you. but like they say your car has o2 sensors for a reason, to make your car run right.

 

The rest of the story, I did add a bung and the other O2 sensor but the light still comes on. I did read the code and it comes back and tells me that bank 1 is out of tolerance. Is this because of the unit missing the cataletic converter? I see many other people put in a header without the converter, do they have the same problem?

 

yes u are always gonna have it on unless u convert to obd 1. the primary o2 sensor controls fuel and the secondary o2 is for catalytic effecincy. so if the secondary reads the same as the primary, then you are gonna get a code for o2
