Sensor arrived quick, other than the fact that Chevrolet gives you NO room to fit a normal size hand to get to the connector, this was easy to install.

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!

Good deal
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.

I installed all them in my home garage less then two hours. Disconnected the battery for two hours. Took the truck for a drive. The check engine light went out in about ten miles. Everything is alright so far. (I am a DIY person.)

How do you tell which sensor is bad?
Mark D on Feb 27, 2016
BEST ANSWER: 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.
