This was my third bank 1 unit not including what came with the Camry. Incredibly expensive considering it was for California about $200 per pop. The original Camry A/F lasted over 15 years, first unit purchased from Amazon was good for about four years, second one lasted a few months without check engine light coming on think it was a knock off and alway had problem passing emission, the third one from Amazon did the trick and pass emission with no issues, so far so good. Watch out, there are three different units on the V8 Camry for three different locations (bank 1, bank 2 and bank 1 sensor 2), all looked the same. California cars must have California sensors at a substantial higher prices. I always buy Denso, Camry OEM. This one located on the bottom of the firewall, virtually no room to replace or apply torque. Be creative and expect a lot of cussing.

I’ve search long and hard to determine which is sensor 1 bank 1 and sensor 1 bank 2. In the OEM market, it is referred to as right or left. My Avalon threw a P1135 code so it is suggesting sensor 1 bank 1. To set things right, right means sensor 1 bank 1 and left means sensor 1 bank 2. Also, I read somewhere that the two sensor is the same but with different wire length. You can take that info with a grain of salt. I ordered 234-9007 for sensor 1 bank 1. As to other reviewer saying the connector is incorrect, this part and 234-9009 is for california emission system. If your car is bought in CA, then this is definitely what you need. You can’t use the other, more cheaper variant. IF your car isn’t equip with CA emission system, then you will most likely run into the wrong connector issue. They put a different connector on the two different emission system’s A/F sensor for a reason. If you install this by splicing the wire into a non-CA emission car, the CHECK ENGINE code most likely will still be present. So make sure what type of emission you have. You don’t want to make a $100 mistake by buying the wrong part. I guess the easiest way to check which emission system you have is with your VIN #.

I own a 97’ V6 Toyota Avalon with California emissions. Denso and Amazon stated that this was the spec’d part for California vehicles. Denso also listed part #234-4622, however #234-4622 is excluded for California vehicles.
Much to the frustrations of other reviewers here I found that this part #234-9007 did not fit my vehicle. The connector plug is different and incompatible with my vehicle. The connector looked the same until closer examination where you could see one side of the plug’s plastic wall is clearly different. Other had stated that there is a sticker next to the hood latch, but that is not the case on my vehicle. However if you don’t find a sticker next to the hood latch it should be located on the firewall on the driver’s side next to the brake vacuum booster. The sticker is white with red writing on it. However be aware that the sticker does not come right out and say Calif emissions, but in the sum of the long paragraph you will get the understanding that if it is a Calif spec’d vehicle it will obvious by this sticker. What is most important is the first sentence:
This vehicle conforms to U.S. EPA and State Of California Regulations applicable to 1997 Model Year Motor Vehicles. Also the bottom left of the sticker will have a”1MZ-FE “CAL” which may be Calif certification, but don’t quote me on this.
Now having said stated the above my vehicle called for item #234-4622. Same plug connector and same build specs. It looked exactly the same as the one that came out of the vehicle. #234-9007 did not look the same as it only had four holes around it circumference of the sensor part as opposed to the many holes in part #234-4622 and the part that came out of the vehicle. The sensor in my vehicle is an O2 sensor not an air fuel ratio sensor which is what part ##234-9007 is. I believe that this is common confusion for DIY as most including myself don’t know the difference between the two sensor but are relying on Denso website to guide us to the correct part, and this is where Denso website fails. #234-4622 should not state “exc. Calif”, and #234-9007 should not state “Calif” as this leads the DIY to draw a logical conclusion for which they should not be faulted for.
When I could not get the sensor connected to the vehicle I ended up reordering the part #234-9007 because the one that I originally received was previously opened and no longer sealed in the plastic bag inside of the box, but was still new. The reason for the reorder was I felt uncomfortable with the items origin and thought that someone had replaced the #234-9007 part with another part number. In fact when I received the item in the mail none of the parts where in the original OEM box. The item was shipped in an envelope and all of the parts where free inside of the envelope, which would not have been a huge problem if the parts where still sealed in the plastic bag. Unfortunately there are no part numbers on the sensor that matched the manufactures part #. This is the case for both sensors #234-9007, and #234-4622. There is a number on the sensor but it is some type of internal Denso number. In retrospect before you begin any work for Bank 1 sensor 1 I would recommend that on a V6 model to disconnect the front o2 sensor’s connector and compare that sensor connector to the new one that you are preparing to install. Examine closely. Remember Bank 1, Sensor 1 is the sensor closest to the firewall on back of the engine. This is also known as the right side of a V6 engine. Bank 1 sensor 1 is determined by where the number 1 cylinder is, and Bank 2 Sensor 1 is determined by the location of the number 2 cylinder. Cylinder 1 and 2 are relative to ignition firing orders
If you order an item and it is not sealed in the plastic bag I would be very leery of inheriting someone else’s problem. So after a second strike with the wrong part I did more research on Denso website and noticed the 96’ model year vehicle called for part ##234-4622 regardless of Calif. or Fed emissions. So I ordered the #234-4622 from Amazon and sure enough it is the right part number for my particular vehicle. I installed the #234-4622 without an issue and it connected right up. The #234-4622 was $30 cheaper than the original #234-9007 part that I ordered but the retail price is higher. Also part ##234-4622 is the same part # for bank 1, or 2 upstream sensors. Another customer in this review stated that he used part #234-4626. I don’t know what that part is for but I believe that it is a downstream sensor. I don’t believe it is for 1MZ-FE engine upstream sensors.
Whatever you do make sure to use a sensor puller/socket such as the “Powerbuilt 648691 Oxygen Sensor Offset Puller” from Amazon it is less than $8 but will save you a lot of grief. I found that installing the sensor from the bottom to be the easiest. If your arm is long enough and not to buff you will be able to snake it up on the driver’s side behind the front tire between the transmission’s output shaft and the suspension. If needed you can use your other arm to raise the ratchet and o2 sensor up to where it will be needed which is right between the rear exhaust pipe and rack and pinion unit. I found this to be much easier and there was no need to start removing hoses and other parts from the top end of the engine compartment. From underneath the vehicle I can get the job done in under 20 minutes.
Just make sure to use jack stands or ramps if crawling underneath the vehicle. Also be sure to use the anti-seize that comes with the new sensor. I recommend keeping the anti seize off o f the o2 sensor part and clean the sensor if needed. They give you an ample supply anti-seize so you will have more than enough to get the job done. If the anti seize was not included with the sensor, as tempted as you may be do not install the sensor without anti seize or else you will have problems if it needs to be replaced again sometime in the future.

The Denso 234-9007 Upstream Rear Sensor costs more than the Denso 234-9009 Upstream Front in sale price for $43 dollars although they look the same. Both were packed in the Denso Trade Mark boxes showing part numbers on boxes. With the sensor 234-9007 when I opened the box, the part inside without Denso logo or part number printed on it. It was hard to tell where it was manufactured and where the components coming from. Both parts sold from Amazon. However it works well for me. Check Engine Alert on dashboard completely turned off for now.

I bought this sensor for a 1997 Toyota Avalon which was throwing a “P0135, O2 sensor heater circuit, bank 1 sensor 1” error code. Add me to the list of people who ordered this air / fuel sensor thinking I had a California emissions vehicle, when I actually needed the Denso 234-4622 oxygen sensor. I bought the car used in Hawaii about 10 years ago, and I think it’s been there since it was new. The sticker on the firewall says “This vehicle conforms to U.S. EPA and State Of California Regulations applicable to 1997 Model Year Motor Vehicles.” as the attached photo shows. Thanks to other reviewers who also thought they had a California model vehicle, only to find out otherwise, I also ordered a Denso 234-4622 sensor so I would definitely have a part that would work. The cheaper 234-4622 sensor fit the wiring harness connector perfectly, and the 234-9007 would NOT have fit.
What was most annoying about this purchase was that not only had the plastic bag containing the sensor been opened, but the tube of copper anti-seize was also opened and was smeared on the part and the inside of the bag. Sorry Amazon, but this one is being returned to you!
