Denso 234-4260 Oxygen Sensor: Ensuring Optimal Engine Performance Review

This is ideal for replacing the downstream O2 sensor (Station 2) on a Toyota 4.7 liter V8 engine. The exchange was easier than I thought! The old one was easy to unscrew with an ordinary open-end wrench, no special tools were required. I saved at least $200 making it myself! (In a 4.7L Toyota V8, there are two cylinder blocks on the passenger side, so the first block is on the driver's side.)

This fixed code P0420 in my 2005 PreRunner Tacoma. I was worried it was the catalytic converter when I googled that P0420 code. I was already looking for an alternative catalytic converter, because the factory one is damn expensive. I continued my research and found that it could just be the O2 sensor. Swap and voila! The code is gone.

Another one has failed but this one is still working. This is Bank 2 Sensor 2 for Toyota Avalon 2005-2009. Denso is an OEM. Without doubt. Be sure to use a CRC connector cleaner and yes, in some rare cases it could be a wiring/circuit or water issue. Sometimes they are difficult to remove. Spray with a PB blaster and ride for a few days, and then maybe another PB blaster before taking it off.

This was the exact Denso OEM part that was originally in my car. Came in retail packaging with a copper non-stick coating. My advice is to spend the few extra bucks and get the exact OEM sensor like I did. This can save you a lot of time and headaches, either during installation (some standard sensors don't have connectors and you'll have to cut off the ends of the old sensor and reuse them) or in the future. A good product.

Corresponds to the original Toyota oxygen sensor on a 2009 3.5 liter Venza engine. He fixed the P0059 trouble code for the oxygen sensor, bank 2, sensor 2. It is very difficult to remove the old sensor, so be patient. Be careful. I used a penetrating rust spray and let it sit for about 3 hours. I watched several videos on YouTube. I used a 22mm wrench. I just crawled under the car so I need to remove both plastic fenders. I cleared the check engine light using an OBDII code reader. Much luck.

I needed a sensor for my Toyota '09 and bought it from my local auto parts store. I paid a hundred dollars and after installing the part found that it didn't work, the check engine light was still on. I took the part back hoping for a refund but this didn't happen, there were no exchanges for electrical parts. The dealer wanted over $150 for a genuine Toyota part. I found a Denso sensor on Revain for less than $60 and decided to order it. Item arrived and fits my Toyota like a glove, the engine

I recently replaced a faulty bank 2 sensor 2 oxygen sensor on my Camry 07 LE. Got it here for practically nothing (on points) and was hoping for a quick replacement using homemade ramps and a cheap 7/8" socket wrench bought here. DO NOT use a 7/8" wrench - use a 22mm wrench instead .since 7/8" is too big and will tear the sensor like mine. Took it to the muffler, lifted it up, lit it up and replaced the sensor for $30. Don't install the sensor right after warming up, just wait a few minutes…
