Here are the items you'll need for this repair: 22mm wrench, jack and jack stands

Raise and support your vehicle. We're using a lift to make it easier to show you what's going on, but this job can easily be done in your driveway or garage at home, on a jack and jack stands.

Disconnect the electrical connector for the O2 sensor. Using an O2 sensor socket or a 22 mm wrench, remove the O2 sensor from the exhaust pipe.

Here we have our old O2 sensor that we removed from the vehicle and our new part from 1AAuto.com. As you can see, these parts have some minor aesthetic differences, but all the major components are the same. We have the same threads and the same socket size. The new harness is actually a little bit longer, but does have the same four pin connector at the end.

If your vehicle is throwing a code for a cat efficiency issue or an air fuel mixture problem, or a code just for a downstream O2 sensor, this part could be at fault. This new part from 1A Auto is going to go in direct fit, just like your original equipment and fix you up right.

Remove the cap that comes on the end of our new sensor. Install it into the threads as far as you can by hand. Finish snugging it up with your 22mm wrench, and reinstall the electrical connector.

Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.
