After I replace this A/F sensor (codes P0051- P2241) will I need to have the codes erased (Autozone) or the ECU-PCM reflashed by Toyota?

Just erase the codes the sensors are the same just straight from manufacturer vs dealer

I just disconnect the battery for 30 seconds then reconnect. This will reset the vehicle computer.

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!

Just because you have an o2 sensor code it does not always mean the sensor is bad. You may have a problem with the wiring or an exhaust leak

o On my Toyota the heated sensor is the rear one. Heated sesors have 4 wires, others have 2. Lee

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!

Same sensor. Just changed out all four using four of these. Went from 9 codes down to 3.

I took my car to O'Reillys auto parts and they put there tester on. It showed the left front abs sensor was at fault. They do it for free.

Hi, I would replace the sensor just to be on the safe side, you need to match the part #s so they work as a team, they did change the system of sending/receiving TPMS DATA around the time of your vehicle, you might need to go online to a VW CC FORUM, you will get more info there, Phil James.

I tried to program it and could not. I took it to the dealer and they told me it was the wrong part. Amazon took it back, no problem there, but it cost almost $300 to replace one sensor. I don't know if I was scammed or not. Proceed with caution.

Find you manual and make sure if your engine is 1MZFE. BTW, there are 4 sensors in 1MZFE, this one is for the code 1135(bank 1 sensor 1) and 1155(bank 2 sensor 1)

are you sure you replaced the senor that was not working? I used onstar to diagnose my problem then looked up the code they gave me on Google to identify if it was the driver side or the passenger side sensor that was malfunctioning.

Hi Graziela, I had this problem as well I took the car to the dealership and after troubleshooting it turned out to be an error from the mass airflow sensor. They told me it was no big deal and they reset the error codes for me. If your car is still under warranty I suggest taking it to the dealership so they can fix that for you, if not, you can take your car to an AutoZone and they can clear those codes for you for free.

You are better off replacing both and this kit will do it. I had the same issue in which I only needed one. But you are hard pressed to find just one sensor that will work. Save yourself the headache and use a kit.

OP, did you ever find the answer to your question? I also have a 2003 camry v6 and got the same P2241 CEL code.

This was a oem AF sensor from nipondenso. Exactly the. Same as the Toyota dealer. I bought two and they work great.

You can take it to a pep boys or advance auto and they can specify which sensor has failed. No charge. They have hand held devices. On my Tundra there are three possibilities.
