Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of Thanks.

In this video, we'll show you how to replace the downstream O2 sensor on this 1998 Honda Civic with the 1.6 liter, 4 cylinder engine and it's the same part and process on these Civics from 1992 to 2000. The items you'll need for this are a new downstream O2 sensor from, a 7/8 inch O2 socket and ratchet, jack and jack stands, and depending on the condition of the vehicle, you may also need wire cutters and a 7/8 inch regular socket.

Raise and support your vehicle with jack stands and then your O2 sensor is plugged in. The harness connection is right there. There's a tab on it, you press the tab and disconnect. Then you can see an O2 sensor socket goes right on and it has a slot for the harness. The only problem is, when it's very difficult, that slot in the socket can cause it to expand and slip on the O2 sensor, so here we bring in a set of wire cutters and clip the harness off right at the O2 sensor. Then we use a regular 7/8 inch deep socket and a piece of pipe to just break it free. Once you break it free it just twists right out.

In the back, is the old O2 sensor. Up front is the new one from 1A Auto. You can see they're identical and they'll mount exactly the same. Twist your new O2 sensor up into place. Then, using your O2 socket, just tighten it up. Reconnect the harness, and re-clip it to that bracket, and you're all set.
