Denso234-9022 Air Fuel Ratio Sensor

Fit well to my rav 4 2012 after instalation no more engine vibration

I purchased this AFR for a 2009 Toyota Venza V6 AWD. This is for code P2197(O2 bank2 sensor 1). The O2 sensor is the one facing you when you open the hood and look down at the exhaust manifold. You will need a socket type O2 removal tool. The ratchet type will not work (limited space). Also note that this part was NOT 100% PNP.Removal and installation is straightforward. Also, never touch the head of the sensor with your bare hands.- Disconnect the battery- Hit the AFR with some PB Blaster and let it sit for 10 min (helps if the engine is warm, not when it is hot; that's dangerous)- Disconnect the clip from the radiator hose- Disconnect the AFR clip from the harness (the AFR sensor is about 1.5ft long)- Use a socket type extraction tool on the AFR and remove it slowly and carefully- Apply the Denso anti seize/grease to the threads of the new AFR and install by hand- If you can fit a torque wrench then tighten it to about 30-33lbs of torque otherwise tighten it till its snug and give it another 1/8th turn- Place the AFR cable back onto the radiator clip, clip that and plug it into the AFR harness- Tighten up the battery and start the carHopefully the 3 lights will be gone. If you have an ODB reader you can check and clear codes but it should still start, work and not have any more annoying traction control disabling problems.Let it run for 5 min to warm up and burn off any remaining PB Blaster fluids. Your ECU should reset so it will be 1-3 gas tanks before the ECU starts becoming more efficient. Your mpg's may drop a bit at this point or it may take a few more cranks to fire her up. This is normal as long as the lights don't come back on.I would have given this 5 stars as Amazon says it fits a V6 Venza but the AFRs wire was about 5 inches short so I just pulled the clip holding the AFR harness in (button clip) and used some zip ties to mount it to a new location. No biggie but Amazon said it would fit and it barely does. At least there's no more lights popping up and my wife's vehicle regained the traction control.On a side note I had to replace the O2 (bank2, sensor 2) first as my ODB reader was saying it was broken. After fixing that then this came up. I wonder how long before I need to replace bank1 sensor 1 as these usually all go out at the same time. Still way cheaper than having the stealership do it. This one took less than 15min and most of that was waiting for it to cool down. Hope that helps.

My car is a 2009 Toyota RAV4 with a 2.5L 4-cylinder engine. I believe this Air/Fuel Sensor, product # 234-9022, is a piece of Original Manufactured equipment because it fits perfectly and it looks the same as the one it replaced. Replacing this item was not difficult. It was pretty easy to screw the sensor off the gas pipe in front of the engine and I was able to do it above the car and quickly. But originally I didn’t intend to replace this sensor. I got an error code from my OBD2 Car Diagnostic Scanner that showed "Code: PO137, Define: O2 Sensor Circuit Low Voltage Bank 1 Sensor 2". I researched the issue on YouTube and other Toyota online forums. I found out that I should replace both Sensors 1 & 2 at the same time. So that was what I did. Sensor 1 was the Air/Fuel Sensor and Sensor 2 was the Oxygen Sensor, product #234-4622. I had a really hard time unscrewing the flawed Oxygen Sensor out of the gas pipe due to a lack of space to rotate the ratchet. In addition, the connector was too high to reach with both hands from under the car, where the sensor is located. You would need one hand to jam a flathead screwdriver into the connector to release the hook, and the other hand to pull the wire out of the connector. There was not enough space for two hands to do this from under the car! Luckily I had my brother helped me out. He stood next to the car and reached down with one hand to take a screwdriver to release the wire from the connector, and I pulled the wire from under the car. After that, installing the new sensor was a much easier step.As soon as I replaced both sensors, the error code went away. Also interesting to note: some online forums I visited have indicated that Oxygen sensors and Air/fuel sensors tend to last about 10 years. That's exactly how old my car is when the error code showed up.I learned about this repair routine from others on YouTube and other online forums, so I appreciate those people's videos and inputs. This DIY repair saved me at least $500 compared to having to leave the car at a repair shop or dealership. As such, I took the time to write this review in the hope that I'd paid my money-savings forward to someone who might be facing a similar problem.

I had p0136 and p0138 codes on my 2012 Toyota Rav4 2.5L engine with 139000 miles recently. Tried clearing the codes, and both codes kept returning so I decided to fix it myself. Now codes p0136 & p0138 stear you to the Bank 1 Sensor 2 O2 sensor. After researching these codes for my vehicle,I found a lot of comments online that said the problem was Bank 1 Sensor 1 Air Fuel Ratio sensor and NOT the Bank 1 Sensor 2 O2 sensor, so I decided to replace the Air Fuel Ratio sensor with this Denso # 234-9022 part. First off, I sprayed the 4 bolts on the Heat shield above the Exhaust intake and the sensor itself with PB Blaster the night before. The 12mm bolts easily came off and I removed the heat shield. The sensor also spun off easily using my Tekton 3/8" drive 7/8"(22mm) offset socket I also purchased from Amazon. After applying the included anti-sieze compound to the sensor, I screwed it on and torqued it to about 35 ft-pounds and reinstalled the heat shield and torqued the 4 bolts to about 12 ft-pounds. I cleared the codes with my obd-ii scanner, and test drove it to get all monitors to display ok and ready, and I have no codes pending and no check engine light after 2 days and 100 miles of driving. So, this part worked excellent in clearing my check engine light even though my scanner said to replace the O2 sensor!

I ordered a new item, but they delivered me a used product. It perfectly fit on my 2010 Toyota RAV4, but I decided to return for a new item.

El producto era igual como en la descripción, llego un día antes y funciona muy bien.

Exact fitment for my 2012 RAV 4 V6 Sport B1S1, located at the back of engine towards firewall. Amazon fitment guide on this product page shows that it will not fit to my vehicle that is incorrect. Amazon please correct this. I am disappointed that the plastic package inside the box was not sealed and i was not very confident to use this product. Any way i replaced it and the error is gone now. So far i drove about 70 KM and it is still working fine with no check engine light. Please note after replacing the sensor my OBD-II scanner was still showing the same code 2195 that i was not able to clear but after driving few km it got cleared by it self. I am also including the exact error i was getting prior to replace sensor so it can help someone else. Big thanks to the user(can’t remember the name ) who responded to my question

Worked well.Tip: Replace both the upstream and downstream O2 sensors at the same time if you have the error codes showing up, even if the codes are only for one of them.

Toyota a changé le O2 sensor, mais les codes sont revenu après 24h. J'ai acheté cette pièce AF sensor sur amazon en lisant sur le sujet de toyota et ces codes, je l'ai changé moi même, déconnecté la pile une dizaine de minutes, et les codes partis. Ça fait 2 semaines, donc je pense le problème réglé.

I got a dashboard light which my code reader showed to be a bank1 sensor1 failure on a 2006 Toyota RAV4 v6 engine. When I installed this Denso sensor the problem was solved immediately.The sensor was difficult to remove because it involves jacking up the vehicle and lying on the floor. I had to reach up under the engine to find the sensor which is located on the bank1 exhaust manifold (which is located on the back of the engine by the firewall). I also needed to buy a sensor socket to do this job. It took me a couple of hours, but I saved hundreds by doing it myself rather than paying the dealer.
