Ok Ht I need ur help I got a 97 civic cx with a b18c1 swap I have a Code=po135 Primary o2 sensor so i thought it was the fact that i didnt have a second o2 sensor and now i wired up the second o2 sensor straight from my ecu and i still have the same code and that one code is holding me up from going to pass emisions which was allready due. do u think its got somthin to do with my wiring???

p.s i tired with another ecu to and i just changed primary o2 sensor like 3 months ago

 

bump bump

 

after hooking it up did you try unhooking the battery untill the code clears? or bring it to your local auto parts store and have them clear the code

 

I didnt try disconecting my battery off and could this be that im throwing code because i have gsr motor with gsr o2 sensors withe ex ecu or should that not matter???
