I have a 2001 Lexus ES300, and my Bank 1 Sensor 1 - is on the rear exhaust manifold located between the engine and the firewall. Bank 2 Sensor 1 - is on the front exhaust manifold near the radiator.Try this link and scroll down to the part about 2003 Avalon or do a Google search with your question.http://www.tundrasolutions.com/forums/avalon/134368-where-my-o2-sensor-2003-avalon/I also bought an O2 socket for about $5 (I got mine at Harbor Freight) or you can buy one on Amazon along the the sensor. The socket will make the removal much easier.

Sensor is located on the back of the engine close to the firewall in the exhaust manifold. You can see it from the drivers side fender.

In my 2000 (likely the same) the sensor was easy to reach, in the front center going right into a manifold close to the radiator. The electrical hookup was to the right. Getting the old out was a bit tough as I had to put the ratchet right up against a radiator hose, used plenty of stuff to try to unfreeze the threads, and I used a cross bar tire iron for extra leverage on the ratchet. The electrical connector was a bit stubborn as well.

I believe Bank 1, sensor 1, is on the back of the manifold and is accessible from underneath the car. Hope this is helpful. : )

I didn't personally install but I believe one is at the front of the car engine while the other is very near the firewall. It was installed about 6 mos ago and is performing beautifully!

When I look up your vehicle it shows the type A 40* sensor, Dorman #974-053.

Mine came with a wide-band O2 sensor and a wiring harness that is over 8ft long. Very complete package.

Ask the company that sells it! But if you go to the Toyota dealer they give only 90 days parts and 12 months on laber and cost around $300.its a good quality sensor.I replaced 3 on my car 1- on 60K second on 90k and 3 on 120k my car is now 135k.All of them I got from Amazon good price!

Single sensor. Put mine in about 2-3 years ago and no issues since. Took approx 1 hr for me and a friend to change in the driveway. Mine were rusted pretty severely. Biggest issue was getting the wiring disconnected without breaking the connectors.

It was the rear O2 sensor on my 2007 Kia Spectra. Thought it was the front. I replaced it anyway but ended up buying a front sensor later.

I know I'm really late on this conversation but as an alternative to the answer from Bill L. is to take your vehicle to an Autozone or O'Reilly's or some other auto parts store that will connect a code-reader to your vehicle for free, make sure the code is from the O2 sensor and have them clear it. Disconnecting the battery on newer cars can be a bigger pain because of all the advanced electronics. At the very least it will save you from having to reset all your radio presets!

Depending on the year of the vehicle it may not matter. My truck used the same O2 sensor in all banks.

Yes it is, sometimes it's called the oxygen sensor, both are interchangeable names. The code identifies what bank and sensor number needs to be repaired, they upstream sensors, relatively easy to change out with a sensor socket.

Denso Oxygen Sensor Part Number: W0133-1815463 This is what I found on Denso website as direct fit for your car Note that this part is oxygen sensor not the air fuel sensor.you also need to find which sensor is gone on your truck There is 4 banks and I think only 2 are oxygen sensors In the moment you know which one and you have the part rest is piece of cake Oxygen sensor wrench can be bought in any car part store for about 12 bucks Wrench is a must have as you wanna protect your wires on sensor

The Denso 234-9021 is an Air/Fuel Ratio Sensor. Used two of these recently to replace both upstream sensors (Bank 2, Sensor 1 and Bank 1, Sensor 1) in my 2001 Toyota Avalon. The trouble codes that were set were P1155 and P1135. Use your OBD II tester to determine which sensor(s) have gone bad. The downstream oxygen sensors do not require the Denso 234-9021 oxygen sensor. By the way, the Denso part was an exact fit replacement and should be money well spent!

The one I brought for my 2001 corolla ce, the mechanic said it would not fit. I brought the front one for my car, oxygen sensor, upstream from a napa company, it was from Toyota . There are two, front and a back.

Hello; On my Pontiac grand prix it was located in the side of the exhaust pipe about in the area of where the drivers seat would be located. So I would call it a downstream sensor (for my 1996 Grand Prix that is).

-go to automotive parts & accessories -enter your car info at the top left -do a search of "o2 sensor" -you'll see all compatible O2 sensors and be sure to read description to see if it's upstream or downstream. -also check to see that it's not a Universal sensor. Universal's typically don't have the connector you need.

Upstream sensors are located before your catalytic converter and downstream are located after the converter. Using the diagrams in the repair help section on autozone.com can help a lot.
