This item's connectors are not compatible with a 2002 Toyota Sequoia as advertised. Separately the vendor has still not refunded my money 7 days after the receipt of the returned merchandise.

My son's 2004 Toyota Tundra with a 4.3L V-8 has had a "check engine" light on for the past few weeks. I finally got around to reading the code and it indicated it was the Bank 1, position 1 O2 sensor. This part was affordable on Amazon and an easy install once I was able to remove the old sensor. The O2 sensor is crammed up along the engine block and the exhaust with only room for 1 hand. I didn't note exactly how long it took me to remove the old one but it was at least 4 hours. 3.5 hours was spent cussing and swearing and trying to get my other hand up from the front of the axle through a small opening. Once I had two hands from different directions, I was able to unplug the sensor and used an O2 socket to remove it from the exhaust. I was surprised that it came right out with little effort. The new sensor, already coated with some antiseize lube, screwed right in and I had to use two hands again from opposite directions to align and snap the connectors together. Bank 1, position 1 appears to be the hardest to reach of the 4 O2 sensors. I cleared the engine code and the "check engine" light is out. Hands are pretty well scuffed up.

Replaced both sensors at the same time, engine trouble light went out and stayed off. Tundra is running better and it appears the fuel mileage has improved slightly.

Check engine light was on for bank 1 sensor 2 on my 07 Scion TC as well as PCM malfunction. Changed the o2 sensor and both codes went away and I was able to pass state inspection. Hasn't come back on yet 100 miles later. This sensor is slightly bigger than the oem toyota part but fits and plugged right in. Cheaper than buying this part from other retailers

Solved my check engine light (P0430 code - catalyst efficiency) on a 4 cylinder (2afze engine) 2002 Camry. I recently replaced the valve stem seals and prior to this was burning some oil (mostly on start up and on long high speed highway trips). I replaced the old plugs and found they were coked with burned oil, and I assume the oil burning also had negative effects on the catalyst. I was told that the Toyota ECU programming was hair trigger on what may be a marginal catalyst and to try replacing the post cat (Sensor 2 on federal vehicles) first. It's much less expensive than a new cat, and if you replace the cat you probably should replace the O2 sensors anyway.Based on advise from others, I was expecting the old post cat sensor (never touched in 12 years) to be very hard to remove. As it turned out, all I had to do was heat the area around the mounting bung slightly (NOT red hot) with a propane torch (I covered the sensor with a wet paper towel). It came out easily with an ordinary open end wrench.The new sensor came with anti-seize compound already applied. It was very close in length to the original. All I had to do was tighten it and plug in the wiring harness (perfect match). I reset the CEL and haven't seen it since! Normally I stick with OEM parts exclusively but this Bosch seems to be a winner for me.

Bosch is a good product. Not high end and it doe's the job. Easy install with sensor socket. Worked out good.

After paying out way too much money for the last O2 sensor I had replaced, I knew it could't be too tough to do this myself. The O2 sensor arrived promptly and I set to installing it. Couple things to remember, there are 2 different types of sensors on a Toyota Tundra, I was replacing the Bank 1 - Sensor 1 side, which is the passenger side on the exhaust manifold. Triple check you order the correct sensor. The only tough part of the whole process was having the right tool. There are 2 different O2 sensor wrenches, get the one that looks like a socket with a slit cut down the side, it is the only one that will work in the space. Warm up the truck a little bit, put on your gloves and loosen up the old one, then install the new one. It is as easy as it sounds.

I had a P0420 CEL that came on/off every couple of weeks. Mechanics told me I needed a new catalytic converter, which is expensive from the dealership. Since it came on/off over and over, I figured it could be the O2 sensor (it's cheaper anyway). OEM fit, just plug in/out. It was a lot harder to pull the old one out due to the location of the sensor on my 03 Camry, but after a long time of trying different tools, I finally got the old one out and plugged the new one in. Cleared the codes and never came back on again after about 10k miles. This product indirectly saved me close to a thousand dollars.
