🔧 Premium Denso 234-9028 Oxygen Sensor - Optimizing Air and Fuel Ratio for Enhanced Performance Review

No need for a detailed War and Peace review. Installed in 10 minutes. I didn't even have to remove the heat shield. Shot with a PB blaster, using the breaker carefully after the motor got hot and the old one popped right out. This sensor is for the upper passenger side on the 01-03 Rav in case you are wondering.

I bought this for my 2001 Toyota RAV4 bank 2/sensor 1 air fuel ratio sensor replacement after the check engine light came on after about 200,000 miles. It works, a short switch later and the light is off. Please remember to double check the part numbers and I have read from lots of research that Denso is the way to avoid disappointment, duplicate work and duplicate purchases.

Ordered this for an OEM exact replacement of a faulty sensor on my 2001 Toyota RAV4. The package came a few days earlier than originally ordered. The one I received arrived in Denso OEM packaging and even had a Toyota part number that matched the defective original part. Once I got the old one (a task in itself) it installed and was working within 5 minutes. While it works great. Excellent delivery service and promised product. Would definitely buy from this supplier again.

The fact that I was able to purchase this oxygen sensor from Revain was amazing. This saved me so much money and it works great. I'm a girl and unlike other reviewers who were able to replace the sensor themselves, I wasn't able to. But I had a mobile mechanic do it for me and it was way cheaper than going to a Toyota dealership or something. I highly recommend this product, especially for unlucky people like me who need to replace all four oxygen sensors in their car. The auto mechanic who…

. This AF sensor is for bank 2 sensor 1 (driver's side before transmission). For me this one was for Rav4 2002 4 cyl. The old sensor lost continuity in the heating circuit and had to be replaced. The original sensor was from Toyota and had a short 4 wire cable. This one from Denso came with much longer cables so I was a bit confused. For a second I thought I had a bank 1 sensor since the bank 1 sensor comes with longer leads. Not sure if it will come with longer cords just to accommodate more…

My 2002 Toyota Rav 4 finally gave out codes P1135 and P1155 after 214,000 miles. These are the bank 1 and bank 2 sensors. I would say it was a good run over the stock part. When I went to my local parts store they charged $180 for an unnamed brand and I asked if it would last half as long as the original part. Well, thank goodness for that part about Revain. Not only is it an OEM part, it's also $80 cheaper. I immediately saved $160. When it came time to install them I was a little hesitant as…

When cheaper non-OEM oxygen sensors couldn't read my car's ECU code "Check Engine" I bought identical parts that were in the car . Factory (Denso, the same part sold by Toyota dealers with a Toyota part number at a huge premium). This is the second time this has happened to a family member's car and Denso's sensors have solved the problem on both occasions. Unlike some cheaper generic sensors, they not only meet original specifications, but also last much longer than generic (or Bosch)…
