Issue with part resolved quickly

March 12, 2017
The original part received was faulty. I believe it had a bad connection at one end of one of the wires. A replacement was shipped out after customer service was convinced it was faulty. the 2 part shipped quickly and resolved the car problem. I will buy from 1A Auto again but cautiously since the parts appear made in China as long as their support remains top notch .

Price was much better than what they offers locally. It arrived on time and well packaged. Plugged right up to my truck, no problems installing. No more check engine light. I would recommend this product to anyone needing it. But I would add make sure it's your sensor first and not something else causeing it.
Great product

Went to the auto parts store to get the check engine light looked at, all codes pointed toward the Oxygen sensor but the store couldn't tell me which one. The cost at the store was almost twice what I paid for on 1A Auto for a single sensor. I purchased all 4 and replaced them on my truck in about 1.5 hours. Parts fit exactly without an issue, check engine light is off now, truck is running a lot better as well. I would definitely recommend and purchase from them again!
Great product

A bit smaller than stock
Joe
April 4, 2019
And what I mean by that, is the sensor shaft that goes in the exhaust pipe is a bit smaller than stock. I'm not sure if this will pose any problems. Above that, it installed easily with the proper sensor socket and plugs in to the old fitting. . Unfortunately after installing the sensor I found the wire upstream of the sensor had been rubbing on the front drive shaft and had worn through the wires; thus setting off the "check engine" light. Make sure you check this first and don't just go by the reader like I did. Installed on a 2004 Avalanche Z71 4x4.
Works great

I always buy my parts from one a auto because I can’t depend on them to ship the right part for a lot less money than my area auto parts stores. Their web sight is easy to maneuver and they make it easy to order the right part the first time. Write your review here. It must be at least 50 characters long. Consider whether you would recommend this product and what you like or dislike about it.

The auto repair place put a computer hook up to the car, it identified a error number (code), that code identified the item. while the engine light did go out for a period of time the engine light did come back on. hope this helps d

I cannot answer that. But the cost of doing it myself vs. Paying a garage to replace, it was worth changing 2 at least

On 2003 Chevy suburban 1500 5.3 flex fuel 4x4 is the upstream and downstream o2 sensors the same?
September 6, 2019
10
Yes, I would recommend replacing all 4 sensors at once. I tried one at a time as I got the check engine light. Ended up replacing the newer one too. Once I replaced all 4 at the same time I have had zero issues. Engine going on 192,000 miles
September 6, 2019

Thank you for your inquiry, for that vehicle the O2 sensors will be the same for all 4 locations. Please contact us if you have any further questions.

Which sensor is this? Upstream or down stream?

It can be either depending on the vehicle it is being installed on. Please check the 'Vehicle Fit' tab to see these details.
