Are these sensors equipped with internal heaters?
Patrick W February 11, 2018
Yes they are.
Tim K March 28, 2018
Do u have to unplug the positive or negative cable before installing o2 sensors ?
Henry G June 27, 2018
Looking for a set of sensors for a 2000 Silverado 2500 with a 6.0. Will these work?
Brian S August 1, 2018
No, this oxygen sensor kit is not compatible with the 2000 Chevy Silverado 1500 with the 6.0L Engine. These sensors are only compatible with the 5.3L engine. Please let us know if you need any further assistance, thank you.
Jessica D August 2, 2018
Good question, but hard to say. They did not fit my 2002 Chevy Tahoe. Their are several models of sensors, and some have different plugs. Depends if the vehicle was made in Canada or the US, or if the parts were made in Canada or the US. In my case the vehicle was made in the US but the parts came from a plant in Canada. Made it very difficult to find the right part. My suggestion is to disconnect the plug under the vehicle, and take a picture. This will make your search much easier. With the picture, my local Pep Boys dealer helped me determine the right plug, and A1 Auto had a much better price. A1 Auto customer service was very helpful as well.
B E August 2, 2018
Would these 4 02 oxygen sensors; 2 for downstream and 2 for upstream work for my 1997 K1500 Chevrolet Silverado 5.7 Liter automatic 4x4 pickup truck?
Jorge D March 19, 2019
These sensors will fit your application as long as it has the 4L60E 4 Speed Automatic Transmission.
Andra M March 19, 2019
Are these O2 sensors 3or4 wire ?
Jimmy H May 16, 2019
These O2 sensors are 4 wire. Please be sure to check the vehicle fit list to ensure they are listed to fit your vehicle.
Anthony C May 16, 2019
Would this fit a 2002 GMC Sierra 1500 4.8?
Jose C July 28, 2019
This will be correct for that vehicle as long as it was manufactured in the U.S. Please contact us if you have any further questions.
Anthony C July 28, 2019
Will these work with a 7.4 vortec?

Perfect fit! Great products and service
I’ve been ordering a lot of parts from y’all. You have great products at a great price. I really like the videos too, thanks y’all
February 16, 2018
Wrong part for truck
Complete wrong oxygen sensors for my truck, even though the listing said "guaranteed to fit". I found that out too late after I had already opened them. Going to try to salvage some of the cost by listing the new ncorrect parts on eBay. I dont know what these fit, but it wasnt my truck.
March 23, 2018
Perfect fit!
My o2 sensors were a perfect fit. For a very affordable price !
April 1, 2018
Working great so far
Working great so far, the sensors fit perfectly and all is well.
April 2, 2018
Good product but not 100% correct
The product was high quality but unfortunently this did not work for all 4 sensors as the connectors were different. This is not 1As auto fault as Chevy trucks some have the flat connector on the pre cats and some have the square. Before purchasing this verify what you have.
April 4, 2018
truck parts
thank you. Our truck is working great again. Will buy future parts from you

Happy with being able to speak with someone about ordering the correct part. Pricing was cheaper than going to a brick and mortar.
August 1, 2018
Junk
Don’t buy the cheap ones, spend the money and get good ones, usually reflected by price. these only lasted about a month and got same codes again, i replaced with better ones and haven’t had a problem since. i would not recommend.
August 1, 2018
So far so good . Glad we found this site . It was affordable and when I wasnt sure about something I called and they were very helpful and extremely nice . I would really recommend 1A Auto . Thank you 1A Auto
September 28, 2018
Worked great and good price too
First, when I was having to buy new sensors I was expecting a higher price so I was relieved to see it wasn’t nearly as bad as I thought it was on my wallet. Installed them without any issues and now my fuel air mixture is where it should be so I’m quite pleased with my purchase ^__^
October 3, 2018
An excellent place to buy parts
I’ve bought from one a auto several times now and it’s always been exactly what I ordered it came early and they have great customer service

2000 Silverado 1500
I purchased 4 Oxygen Sensors for my Silverado. Thanks to 1aauto I have achieved 312,000 miles and plan on getting many more on this truck. Thank you
November 22, 2018
Great price
Well very good part so far and if you take the time to do this, well lets see over $250 a plug for a mechanic to do this and not sure if service engine light will go off or not, or $75 and then have to get some special tools which was only $12 to $40 dollars, well light came on again but computer pointed this out and then EGR valve next and computer is only telling me ABS now, which God has blessed me with the ability to brake, so worth the time and the money to lift my hands and feet and make the computer on the horse happy.
November 25, 2018
O2 Sensors
Not sure if the quality of the product was the problem or if theres another issue, installed the sensors and cleared the codes. Same codes popped back up and having the same problem. Now as for the process of ordering, product came in a timely manner and each sensor was individually wrapped. They were not marked as which was which, had to figure that out on my own. Ill definitely be ordering more products. Im pretty sure my truck is the problem and not the product I ordered. This truck has been giving me problems in the past few years and I think its just time to part ways with it.. I just love my 01 Yukon XL weve been all over the USA together.
November 29, 2018
great value
Parts fit perfect and as always a great value. The free shipping is a great added bonus.

O2 sensors for 1999 Suburban
Received the sensors within a week of ordering. Watched the video, which was very helpful. Replaced the upstream sensors, the one on the engine side of the converter, and within a few days the service engine light turned off and the vehicle started running a lot better. I would recommend these highly.
January 5, 2019

99 GMC Sierra o2 sensors
Saved me $100 if I had went to the local parts store. Sensors came in just a couple days and new on packaging. Would definitely buy again
March 7, 2019
02 sensors
Good product so far seems well built. Only negative thing is the upstream sensors are not direct fit. You going to have to spice them in use your old connector end.
March 11, 2019
Very satisfied
The part was very helpful and I would recommend anyone to try this company, and the prices are great.
March 18, 2019
Not correct for the 2004 Yukon Denali.
In looking up the year and make O2 snesors this is what pulled up. I went to install and found that all the connections were different. Quailty of part looks good. How well it functions, i am not sure. Shipping was good So due to the fact i did not look at my connections first i ended up with 4 sensors i can not use. Will look int returning them.
March 31, 2019
Great price and easy install
This was much less expensive than buying from local auto parts store. It came pretty fast and was easy to install would recommend

Good customer service
I ordered o2 sensors for a 2002 Yukon. I received the wrong parts but A1 researched what went wrong and at the end of the day issued me a refund. I also didn’t have to hassle with sending the parts back. Even though the parts were incorrect they did great on the service side. May buy again in the future. Thanks
April 5, 2019
Good service, Good products

DOES NOT FIT 6.0 GAS ENGINE
i ordered these because after entering my trucks info this is what came up. once i took one out of the package i notice that the wiring was incorrect for my 2000 3/4 silverado 2500 6.0 gas engine. they were shipped fast and appeared to be great quality, they just didnt fit my car. at first they werent going to let me return them because id opened the package. I explained that the only reason i ordered them is because their website told me to. they eventually allowed me to return them. i am still waiting for the refund. it has been roughly a week or so.

1999 Yukon , with 345,000 km. 5.7 vortec flashing several codes.
My high miler Yukon was flashing multiple codes. I ordered the complete distributor along with the 02 sensors. I was very pleased with the shipping time , as well as the pricing. My local trusted mechanic did the install. The codes have all disappeared, my Yukon starts first time every time, the accleration is crisp and smooth, the exhaust tone is also deeper and the fuel mileage has improved. There is no longer that noticeable raw fuel stench at idle. I am very satisfied , I will definetly place furrher orders . Thank you for a job well done. Cheers.

Great service from this company, the part was a wrong fit and return was an easy process, sadly they didn’t have the right replacement so paid for return shipping and got my money back. I will be using them again

A+ for 1A Auto
First, my 18-yr old Son and I are working together to update his 1997 Silverado, 5.7L, C1500, OBS. This is a great opportunity to spend some father/son time together during this pandemic. I teach him. He teaches me. This build is all on him and he is footing the bill (yes, him). This will become his pride and joy. The 1A Auto online system is second to none! Even the national box stores cant beat the pricing. We like the fact we can get what we need quickly by putting in some basic information (website is very intuitive) or add all the details (such as VIN or product Number) as possible and it guides you to the variety of product manufacturers (OEM) for your vehicle. The Fitment confirmation system is a great add-on for us DIYers to get it right, the first time. From time to time we have had to watch the product installation videos that are simple and direct. The YouTubers are fine but have a tendency to be too short, too long, skips important information, or poor video/audio quality, etc. There has been a couple of times we have needed to call 1A Auto to confirm parts or additional installation components for the job. The folks in the technical group are incredibly knowledgeable and they will not steer you wrong or up sell you. They have even suggested 3rd party product vendors they dont sell (like, Custom Brake Line providers for custom lengths for lifted vehicles) to help get the job done right, on-time and within budget. The emails seem to be AI (artificial intelligence) as 1A Auto seems to know what project is next. I will be damned if I know how they do it. 1A Auto, keep up the great work, professionalism and aggressive pricing. It seems we have an on-call mechanic adviser. If you order online like we do, get the order right or missed something, I have had Michelle in Customer Service contact me to confirm whether I needed sway bar linkages to complete the order and complete the job. Our products come well packaged, correct amounts, and at a very fair and responsible price. Remember, its my Sons money and he thinks his is worth more than mine. Thank you 1A Auto keep it real.
