Apologies for restarting and old thread, but the tutorial is an excellent one and worth keeping in play (I expecially like the suggestion to practice on a similar, but easier to reach, connector before attempting the connector for the sensor).

I found it much easier to use a ($4 bargain import tool store) 22mm box end wrench, as the OP did, rather than one of those crowfoot gadgets or slotted sockets made specifically for sensors. There really isn't much room to use a ratchet drive, and even if you can squeeze on in it will be difficult to apply the necessary torque to loosen rusted-in sensor. The 22mm slips on easily, with the handle hanging down below the bottom of the car, making it easy to apply however much force is necessary .

I used the $36-at-Amazon univeral Denso sensor. I started out by trying to solder it, but the solder wouldn't stick to the wire so I decided I'd rather have a good crimped connection than a bad soldered one and used the crimp connectors provided. I was glad I did - the connectors seemed very good quality, and the shrink tube the deluxe kind that has a heat-activated sealant inside to make a completely waterproof seal, so they should make a durable connection that will last as long as the sensor. One thing you should not approach the job without is a good crimper - not one of those cheap stamped ones that come packaged with $4.99 connector assortments, and especially not a vise grip or regular pliers. I used a nice $6 forged steel one, from the same bargain import tool shop where I got my 22mm box end.

great description.

Very helpful.

Here is my experience with 2006 Limited V6.

I had code P0137

And purchased these:
Amazon.com: Denso 234-4261 Oxygen Sensor: Automotive
Powerbuilt 648691 Oxygen Sensor Offset Puller : Amazon.com : Automotive

The sensor is right behind the front bumper. (I found another one in the middle bottom of my car, but that's not the right one.)

I used a small piece of pipe to extend the wrench on the offset puller to screw it off.

Thanks for the tips here, really gave me useful hint to get the job done.

Hello, I have a 2010 RAV4, limited, V4. My bank 1 sensor 2 light came on. I've changed my own brake pads but nothing else. It seems like an easy change - but I'm unsure of the location and all the imagies on the forum are missing. Any advice? Thanks

I've read there is a bank1 which is driver side and 2 sensors per bank? I bought the owner repair manual and it reads for 4cyl there is 1 cylinder bank except 01 to 05 2 per ... So bank 1 , sensor 2 is driver side after the converter ??? Am I ball park

 

[MABMBA]

Before my converter I found one sensor driver side off the right side from the front of the car exhaust manifold and the other passenger side on the front exhaust right before the converter from the bottom. I've never done this before so I bought the repair manual which states that all other 4cyl models outside of 2001 - 2005 have one upstream sensor and one down stream sensor .... Based on my photos am I reading this correctly ?

These were great instructions and I was able to replace my sensor following them. I referred to them many times during the process.

Some notes:

Autozone had a part glitch, so be careful and make sure you get the Denso 234-4622. I ended up with a o2/fuel ration part and didn't notice until i was trying to plug the sensor back in.

I also had to use a lot of PB Blaster and tapping with a 3lb hammer to get the sensor free, but after that everything went according to the instructions above.

I have to do this same sensor replacement. I dont understand - the original post says it includes pics but they are missing. Where are they?

 

[buckjs1]

Were you able to see the pics..I think I had this problem one time, but I either wasn't logged into the site or had to refresh my browser. I still see the pics at the beginning of the thread.

How can I find Toyota OEM part number for all 4 oxygen sensors? I have 3 bad ones, but I cant find a good website that shows exactly which part number goes with the correct bank# / sensor#. What's a good Toyota website to find parts?

What is the torque rating for the Oxygen Sensors? I torqued them to 31 lbs/ft.

I have smoke coming from all 3 O2 senors after replacement. I ran it for about 15 minutes, fully warmed up, went for a test drive, and came back and still have smoke. I thought it was PB blaster burning off, but after so long, I am not sure. I did spray them about 3 different times, just to make sure they were good and soaked, but I think it would burn off faster than that.

What do you guys think?

This is a new-to-me 03 RAV4 with 155k miles, 2.0L, FWD, Auto. I have not registered it yet, so I can not drive it and report back.

I can't think of anything else in the area that would smoke, so it's probably the PB spray. Assume you looked for any oil leaks?

Thanks so much for this. I'm looking to replace the rear oxygen sensor on my 2012 RAV4 2.5 L and this is a great walk through. I do think the pictures you included are no longer here though. I am pretty sure I have spotted where the sensor plugs in, but haven't been able to find a good picture. If you might have 1 still, I'd really appreciate it. Thanks!

For Bank 1 sensor 2. Look under the front passenger door and Follow the exchust pipe to the front! Its near the front axle and tire. You can't miss it.

Perfect. Just wanted to make sure I was looking at the right thing. Thanks for the pictures too!

Thank you very much. Very nicely done.

Just wanna say thanks to sean20202020. This guide has definitely helped me and all of us.

It's 5 degrees outside with some snow and ice. I was underneath my car the whole day. It's a tricky tight spot in my opinion. GOT THE JOB DONE WITH SOME FROSTBITE AND PB BLASTER ON MY HANDS

Why didn't you wait for a warmer day? Kind of crazy doing it in this kind of weather!
