Is this an oxygen or an a/f sensor? Looked up my part it points to a/f sensor. bank1 sensor 1 is what I need.

I'm assuming you need the sensor for a Lexus RX300. If so, the important thing is part number: Denso 234-9009 which designates Bank1 Sensor 1. Make sure it's a real Denso sensor and not a third party knockoff. Denso is the OEM supplier for Lexus RX300. Oh, and if you install yourself, make sure you pull the fuse for the sensor or remove the ground from the battery to reset the computer.

There is an MAF sensor and an O2 sensor. I replaced both of them in my 2000 Avalon. The MAF sensor was easier, despite what I saw on blogs, all I needed was a phillips screwdriver. The o2 sensor was easy to reach but very stubborn to get out. After replacing the MAF sensor (second) I was able to get the car inspected (and the engine light stayed off).

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

The front sensor is the air fuel sensor. The rear sensor is the oxygen sensor. I installed both. Easy Job. My check engine light condition was fixed! Denso makes great parts and they fit EXACTLY

2000 Ford f150 5.4L regular gas This part number 15717 is specified for the downstream; bank 1&2, sensor 2 in both cases. Part number 15716 is for the upstream sensors(sensor 1), either bank. These are original spec, exact fit, california approved O2 sensors. They do an excellent job. The downstream sensors can be replaced with a standard box or open end wrench. (I forget the size, 7/8 I think) very easy, takes all of 5 mins each. The upstream are in a much tighter space, especially the passenger side. Passenger side btw is the number 1 bank. Driver side is the number 2 bank. I highly recommend you get the short offset O2 sensor socket wrench. Powerbuilt 648691 Oxygen Sensor Offset Puller or something like it.

I have an F150 with the 5.4 engine that is positioned longitudinally, so my cylinder banks are oriented right and left. The o2 sensor on the engine side of the cat is #1 and the sensor downstream of the cat is #2. I recommend you go to the Bosch Auto Parts web site and look up your vehicle. It specified this sensor for all 4 locations on my vehicle. Yours may require different length electrical connections (wires) to connect to the #1 vs #2 cat.

I just changed my sensor and my light is still on, call up denso customer service line and tell them which bank and which sensor it is (señsor 1 or 2) and they should be able to confirm before you buy it, I advise DONT buy any sensors until you confirm which one it is, I believe on our gs there are a total of 4 02 sensors

What I try doing with all of my home repairs is replace the cheaper to replace items first if you cannot properly identify exactly what is wrong. Codes will point you in the right direction sort of yet vehicles are very integrated with everything affecting everything else for the most part. YOu can very easily test the voltage/resistance (Look it up online) to positively identify if your O2 sensor needs replacing.

As stated earlier Sensor 1 is air/fuel this is not the air/fuel sensor. What is the check engine code number?

If your engine is a 1MZFE. There are 4 sensors, 2 in each bank. Sensors have factory connectors, no modifications to wiring required.

Yes the one I ordered was downstream. Dont forget to get an oxygen sensor socket as well.usually $20 but your parts store might have a loaner program that has one in their inventory.

I ended up doing both O2 sensors because it was cheaper. But less than a year later my rear cat converter is done and needs changing. I have 235,000 miles on though... I passed emission a month before the P0420 code came back, then it was my cat, so... I think the sensors were bad too... hope this helps!

For my Toyota, Denso is OEM equipment. The part number was legible on the sensor I removed. It is my belief that the term oxygen sensor and air/fuel sensor are the same thing. Check out Densoaftermarket website for better clarification.

Sensor 1 is always before the catalytic converter and Sensor 2 is always after the converter. On the RAV, sensor 1 is high on the manifold/catalytic converter (accessible under the heat shield), while sensor two is accessible underneath the vehicle (remove the black plastic piece connected to your bumper).Bank 1 is on the drivers side, and bank 2 is on the passenger side.http://www.toyotaownersclub.com/forums/topic/128709-2000-rav4-1az-fe-o2-lambda-sensor-bank-identification/

There should be two o2 sensors. One before the cat and one after. For my car (03 Focus) the 15717 went before the catalytic and the 15719 went after.

There are (4) O2 sensors two of them upstream of the cat converter, and two downstream of the unit. They are different part's, so there will be two part #'s. 2 of each. Amazon has the best price out there so get them there, and get the AC Delco brand. Another bit of info while we're at it, you will need to get a metric plug to block off an extra hole on the downstream side of the unit. I have no idea why flowmaster put in the extra hole, and why they did not include it the kit if this assbly has other applications. You can get the plug at CARQUEST, it is the same size as the O2 sensor, 18mm if I remember right.... Also cut the (6) nuts off with a grinder on the ex manifolds or may risk the chance of breaking the studs. Then you have to pull the manifolds. It took me (2) hrs to do the job lying on my back, but it came out perfect!!!! Good luck.

You can buy a oxygen sensor socket. It has a groove on the side of the socket to allow wires to move as the sensor turns in the socket. This is a universal part.
