how do i swap 1998 honda civic sedan secondary 02 sensor?

10-23-2007

I know the secondary plugs into the cat converter, and I know the wires go up into the car through a grommet. What I don't know is where those wires terminate and how do I get to them? I want to be able to remove both ends of the 02 sensor and replace the whole thing. I tried tracing the wires but can't seem to find where they go.

There is a connection somewhere in the line. If there is not, then look for a splice where the sensor might have been changed in the past and the person replacing it cut the wires on the wrong end of the connector, so just spliced it in. It should come out of the exhaust pipe really easily with an O2 sensor socket.

im pretty sure that grommet pops out and there should be a plug on the end of the wire and the new O2 sensor comes with a new grommet im pretty sure if you get the better one
