I need help finding the plug for the 2nd o2 sensor plug(the one connected to the cat) i have a 99 civic coupe

 

Its on the Cat, then the wires run up about where the shifter is.

 

Are you sure? i took off the cover for the shifter i can't find the wires

 

there will be a rubber peace right above the cat where the o2 comes out pull this down then you will have to fight with the wires a bit and the plug will come down when you get it there u will have to move it a bit but it will fit throe the hole i will try to tack some pics to night and get back to you if you still need them

 

ok thx, ill try to pull that rubber piece out

 

don't do it from inside the car, get under and u will see it its impossible to miss

 

thanks a lot guys! hopefully this is the problem with my check engine light

did you pull the code to make sure it is...? Check the code first before you bother doing all this.

 

i tried pulling the code, but it wouldn't let. i believe it is because i have jdm ecu.

 

dude ur 2nd o2 sensor has nothing to do with ur engine or much, its just their to chk if ur cat is working which I thnk u could care less, the code will come up and show it though, but no need to fix it since the main sensor is the main player, but its up to u if u want to chnge it, its really east anyways
