check engine light trobble.

[chinoman44]

ok i have a 97 honda civic sedan and i recently installed new ebay header becouse my old ones cracked becouse of an accedent. the problem is that ever since the new header was installed i have a check engine light, i run the diagnostic and it's telling me that the problem is my rear o2 sensor but everything is in it's right place and working order. what can i do to fix this?

[civic510z]

have you try reseting the ecu by unplug the neg. battery or taking out the ecu fusl.( i just cant spell right now brain fart smoke to much )

[achilles1981]

do you still have the old cracked header? If you do, and you never got the recent recall intalled, put those fuckers back in and take it to the dealer to get new ones. Otherwise, I dunno what to tell you.

well i did do the rest like a thousand times and it would be off for a couple of days but then turn back on...is there a piggy back that i can run to throw it of becouse i really dont need that sensor i just tired of look at the check enginge light.

[cory jordan]

what ecu do you have. have some one take out the 02 out of the ecu.

i had the same problem
i disconected the battery for about 15 min and it went away.hope that helps

me too and did the disconected battery thing and hey it worked!!! or like they said reset your ecu if the battery thing do not work

If you got rid of your cat the second o2 sensor is just trying to tell you that its not working...

[civic510z]

i heard people can buy a 02 sim. for the second o2. i get rid of the check light

Yea, you can do that...or you could get your ecu chipped and have it removed...i know there are other cheaper ways to get aroud it...i just cant remember what they are

[chinoman44]

well i still have a cat for now. and everything works it's just that stupid like that stays for the rear o2...
