Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you oxygen sensor replacement. This is the rear oxygen sensor on this 2003 Honda Civic. The only items you'll need include a new oxygen sensor from 1AAuto.com, and we also sell the oxygen sensor socket.
Raise and support your vehicle.
Then locate your oxygen sensor in the center of the rear cat converter. Locate the connector for your oxygen sensor on the passenger side of the firewall, just above the subframe. Release the retainer and disconnect it. Remove it from the retaining clip and let it hang. To remove the oxygen sensor, we'll be using this oxygen sensor socket from 1AAuto.com. You can see here that it has a small window cut out of one side of the socket that allows for the sensor wiring to rotate around without being crushed, pinched, or otherwise damaged in the 6-point socket. It uses the standard 3/8ths drive, or you can put a bigger socket on with a 1/2" drive for a little more torque.
Here we have our old oxygen sensor from our vehicle, and our new one from 1AAuto.com. As you can see, we have the exact same threads in sensor. Our new one actually comes with a little bit. Never Seez on it to keep it from getting stuck in the catalytic converter. We have the same 4-pin connector, and the same rubber boot to attach into the retainer on the firewall. This is going to go right in, direct fit.
Here's our new sensor from 1AAuto.com. We'll go ahead and start those threads into the cat converter by hand. Bring it down the rest of the way with our sensor socket. Be sure, especially when installing the new sensor that the wire can rotate freely, so it doesn't get pinched, twisted, or otherwise damaged during installation. Torque the sensor to 33 foot-pounds.
Reinstall your O2 sensor connector at the firewall. Be sure that it clicks, then install into the retainer. Be sure to leave a little bit slack on both ends of the line.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.
