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 1AAuto.com. Thanks.
In this video, we are going to show you how to replace the downstream O2 sensor on this 2003 Nissan Altima with the 2.5 liter, 4 cylinder engine. The items you will need for this are: the new downstream O2 sensor from 1AAuto.com, flat blade screwdriver, and 7/8 inch O2 Socket and ratchet. Depending on the condition of your vehicle, you may also need: wire cutters, and a 7/8 inch socket, just the regular one.
Your downstream O2 sensor is right here and connects right here with the blue harness clip. You want to pull that off that bracket, push the tab, and disconnect the harness. Put your O2 socket on to that O2 sensor and you want to just remove that. In some cases the sensor's in there too well and the O2 socket can't do it. So what you need to do is: you are going to have to clip the wires and use a regular 7/8 inch socket instead. So, like I said, if it doesn't come out, you just want to use some pliers or wire cutters and just clip those wires, pull them off. Now, using a 7/8 inch regular socket, you can just remove that O2 sensor. Use a piece of pipe or breaker bar for leverage if necessary. Then we'll fast forward as Don removes the O2 sensor the rest of the way.
On the left, is the old O2 sensor; on the right, is the new one from 1A Auto. You can see that they're identical. They will plug in and connect exactly the same. Run your new O2 sensor down into place and just twist it in. We'll just fast forward as Don twists that in the rest of the way and then, using the O2 socket and ratchet, tightens it up. Then reconnect the harness and just clip it back on to that bracket and you're all set.
