is for my aftermarket high flow cat.
there's two black wires, one green wire and one white wires

 

stupid post, someone answered me already, dam_ me..newbie

 

what year is your car. and are you trying to bypass the secondary or primary o2

 

it's the o2 sensor plug into the oem cat.
i got some aftermarket one doesnt come with the slot.
my car is 2002 accord SE coupe.
thx

 

Well to get rid of the Check engine light for the secondary o2. you need to trick it. by tell the ECM that your 2nd o2 is reading a voltage where it knows that your are not polluting the air. basicly your high flow cat is almost like a test pipe. the obd2 and up stuff reads it to tell you to go fix your cat.

We make a unit that tricks the comp. we sell it for 90... email us if you interested

em...i think i saw couple of post where the guy hook it up with some resistors.
I wrap the sensor with foil and now it's okay now..

 

Iam7head, did ur OEM cat go bad or something? must have gotten it for performance, the high flow cat, cuz ur car is very new still, if u need an o2 sensor man in case cuz urs went bad, which i doubt, i have one, for a 6th generation accord coupe, the one on the cat, as well as an OEM cat.

 

No The cat and the sensor is in perfect condition. thank you tho'
I got the high flow cat and that's the problem.

 

Still struggling with the dumbass o2 sensor..help!!!1
