Tools used
Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Open the hood. Pull the release handle down here above your knee. Release the safety, which is right here. This hood had hood struts. On this PZEV Camry, bank one sensor one is at the top of the exhaust manifold here. The wire goes over here to the connector. And can just see the connector. And you can just get to the lock port, it's kind of difficult. I'm going to remove the air box, just slightly out-of-the-way so I can get to this connector better and undo it before I remote the O2 sensor from the manifold.
Use a 10 millimeter socket and ratchet to loosen this up. There's a second one on the backside. Unplug this electrical connector here. Unplug this one here. This harness is actually connected to the air box, so can't pop it off. I'm just going to leave it here and move it to the side. Loosen this clamp, the intake tube. Lift up the air box. Make sure those are fully released. Take our air filter out of here so it doesn't get damaged. This harness here has a little push connector. I'm going to take these needle nosed pliers and just push them together. And just pop it out and put it aside. Put this aside so it doesn't get damaged.
Can see the sensor connector here for the O2 sensor. Push in the lock. Need a flat bladed screwdriver to push the lock open. Push the lock open with a flat bladed screwdriver and work the O2 sensor out, just like that. To un-clip it from this clamp that's holding around the upper radiator hose, going to squeeze these little tabs together. Just kind of unlock it. Just leave that in place. Lift this up. Pull it out of this clamp, this metal clamp. It keeps the wire from touching the hot exhaust and melting, so you'll want to keep that and use it. It should pop right off of the O2 sensor. We'll just put that over here.
I'm ready to remove the O2 sensor from the exhaust manifold. This is a 22 millimeter on the O2 sensor. Luckily, it's actually big enough for the connector to go through, so you can slide the box into the wrench on there. Get it seated. Give it a nice pull. There's the O2 sensor.
Here's the old O2 sensor and our brand new one from 1AAuto.com. The same length of wire. The same style connector. This should fit in the vehicle and work great for you.
The O2 sensor does come with anti-seize on it. I'm going to add a little extra copper anti-seize to it just before I install it. Make sure you keep it on the threads and away from the sensor tip. Hold the wire up. Thread it in by hand. You have to spin the wire around with it. Make sure the thread's in nice. Take a 22 millimeter wrench and just tighten it up until I feel the gasket crush. I'm going to clip this little bracket back on to place. Snaps over just like that. Clip my wire into it. Keeps it away from the exhaust manifold. Run the wire down over the plastic clamp, just like the original. Clip it back together. The connector is here. I'm going to line it back up just like the original and hold the back of this connector and push together so it clicks.
Reinstall the air filter. Take the upper air box. Connect those tabs underneath that lock it into place. Push it down. There's an alignment tab or opening here on the rubber hose that matches up with this tab here. I'm going to push this down. It should slide right over. Make sure that this claim is seated in the grooves. Tighten it back down. Reinstall the bolts that are holding the air box cover down. Don't forget the one in the back. Finally, don't forget this harness. Plug it back into the air box where I pulled it out of. Put it back into the mass airflow meter. Plug it back into this connector here. The air box is reinstalled.

Worked great!
It fits exactly for my matrix
Needed a new O2 sensor (upper and lower bank) for my 2007 Toyota Camry. I ordered and it came in time. I changed it and my car runs even better.
It's an O2 sensor. I swapped it with the current one. Less than a year into it, I started getting a CEL. I do normal troubleshooting by clearing the codes. The CEL immediately came back. The code reader pointed directly to this part. YMMV
I've been purchasing parts from 1Aauto for number of years now and have had perfect fits on every part and when I needed help with purchase the employees have made it very easy
The first think I did check the length of the cable second the plug connector third compared completely with the old one before installing the new sensor I erased the check engine light and everything went back to normal. Thank you 1A Auto
Quick shipping and easy to install. Great price also.
Good quality!
The O2 sensor worked like it should
Good product.
This is an oxygen sensor.
Yes, this part will replace the Upstream Oxygen sensor on your vehicle. There are 2 oxygen sensors on your 2004 Toyota Camry 2.4L.
Yes this is California legal.
Hello, I apologize we would not have this type of informtion. You can try looking in your owner's manual or contact a mechanic locally for that answer.
This vehicle will have four oxygen sensors.
