Denso is the OEM maker, so it fit perfectly, 2nd time changing them, but to be fair the car is over 220k miles, so hard to ask for more than that!

This product caused a different engine light warning in my car after installing it so it took a while to to realize that this was the problem it is past the Amazon return and Denzel will not honor warranty

I got this O2 sensor because Denso is the same brand Toyota uses. I’ve read in online forums that other brands don’t work as well. It was my first time installing O2 sensors, and the job was straightforward since I found a YouTube video explaining the process. I would give 4.5 stars if I could, only because Denso doesn’t include vehicle-specific directions either in the box or on their website. It would have been nice if Denso told me what wrench size is needed and that removing a heat shield is necessary on my ‘03 Corolla. 7/8” wrench worked great, no O2 sensor wrench needed. 22mm would have worked, too.

I used this item in my Toyota Matrix 2003 XR. It was delivered, fast and well packaged with its product that should be applied to protect the sensor head when it's installed into the engine.As far as it's being under test until today, it works fine, and enhanced engine performance and consumption.I recommend it, as it's a quality/price deal.

Not a mechanic, this was a first for me. Was able to replace with NO issues or special socket needed. 2004 Toyota Corolla S, disconnect battery- remove 4 12mm nuts to remove heat shield- unplug upper wire, 22 mm box wrench and lots of room for box wrench. Remove and reverse to install new part - yep I forgot to thread the electrical wire though the heat shield on my first attempt to reinstall - easy fix - then reinstall heat shield. Reconnected the battery - turn engine on - no more engine light - and car runs great!

This sensor is identical to my original Toyota sensor.The price was awesome. It was about $50 cheaper through Amazon then Lordco.Also came with anti seize for the sensor. I used it on a few other bolts too.I had a lean air fuel mixture code and a slow sending Oxygen sensor code for sensor one (upstream).Install was quick and easy for my Toyota Matrix.You don’t need the oxygen sensor removal adapters if you take off the heat shield which is only 4 bolts and adds about 10 mins total to the replacement of the sensor. On my Matrix it was a 7/8 wrench.

I got the P0133 (o2 sensor slow response) code twice in a roll (after manually cleared it with an OBD II reader). Although the code doesn't mean immediate failure, I did not want to take the chance for the engine to stall in the middle of the road.I have searched for other cheaper options (around $30), but experience tells me that when it comes to mission-critical parts such as the oxygen sensor, you just have to go with premium priced OE parts.This part is like the engine, which never stops working while the car is running. A cheaper part might work initially, but there is no guarantee it can last; you wouldn't risk the engine stalling in the middle of the road to find out, would you?This sensor came with a small packet of anti-seize, which is really helpful for future replacements. I spent an awful amount of effort trying to get the old one out, and it turned out there wasn't a single application of anti-seize on its threads. The old sensor was covered with carbon deposit, and who knows what is going to happen had I not changed it in time. The new one fits in perfectly, and the check engine light never came up again after replacement.To summarize:Don' t go cheap on mission-critical part such as this upstream O2 sensor; it controls how much fuel the engine is getting, too much or too little fuel will result in increased fuel consumption, as well as increased emission of harmful pollutants.

This part fit perfectly and functioned well but after a couple of weeks I am getting a slow circuit error code. So not sure if it is the sensor or something else. After searching the internet, the majority of the answers point back to the new sensor. I just clear the code and move on.

This product worked perfectly for solving my emissions related error codes on my 2003 Toyota Corolla LE (manual). This product is the upstream O2 sensor located under the hood at the back of the engine compartment. My check engine light appeared so I had the car inspected by 2 mechanics who pulled the error codes with their OBDII scanner. I had the dreaded P0420 code (cat converter) plus 3 others related to the evap system P0440, P0441 and P0446. They both said I need a new cat converter and evap canister. The parts alone are approx. $1,200-$1,400 for the factory catalytic converter and about $385 for the canister plus labor. So probably around $2,700-$3,000 for parts and labor. I did a lot of research online, watched youtube videos etc to find that Toyota Corollas notoriously throw these codes for emissions. Sometimes replacing the gas cap alone will clear all of your codes so do the folling steps in this order if your Toyota is throwing these emission codes. 1. Make sure you have a factory gas cap (very important) always turn gas cap until it clicks, never overfill gas tank or top off the gas tank, it will ruin the evap canister. Stop pumping gas when the pump automatically stops 2. replace both upstream and downstream O2 sensors, Denso makes the best non factory part at a great price. The sensors come with a small tube of Anti sieze lubricant which you must use on the threads, do not substitute with brake grease or other lubricant. Unplug all emissions related parts including both O2 sensor and egr sensor, spray all electrical contacts with electric parts cleaner and reconnect. I also purchased a 7/8" O2 sensor socket adapter which really helps out, access is tough with a regular wrench and it's cheap to buy. Usually appears in the Amazon 'customers who bought this also purchased...' message when you buy the O2 sensors. Once both O2 sensors have been installed, you'll need to reset your error codes and then drive the car for approx. 20 miles to see if they reappear. You can have AutoZone read ODBII codes and reset OBDII codes for free. I bought an app for android phone called 'Torque Pro' (4.99) and a bluetooth adapter for my OBDII port ($14.99 on Amazon) to read and clear my own codes. OBDII scanners are usually $100-$140 from auto retailers. In conclusion, after worrying about these issues for about 8 months, I installed 2 new O2 sensors and a new factory gas cap, cleared the error codes and passed my emissions test with flying colors saving myself about $2,800. I highly recommend trying this first before replacing the cat converter and/or evap canister.
