Bosch 15282 Premium OE Fitment Oxygen Sensor - Compatible With Select 2003-17 Buick, Cadillac, Chevrolet, GMC, Hummer, and Saab Vehicles

Installed both upstream because the scan showed code implied it may be what is causing the engine light to be on. Started first with the MAP sensor then these. The MAP sensor did not solve the problem and at first after installing these the light was still on, then driving the next day the engine light went off and stayed off problem solved. I heard it may take a few starts. Great product,

What owners of the 2003 Hummer H2 need to know: This is the oxygen sensor pair on top. The plug terminals are not the same as the ones on the bottom. The product quality is very good, I recommend it.

Worked perfectly no more service engine light.

Worked fine for a month, then had to go on long trip. Engine light comes on and codes P0151 and P074 show up. After checking all possible reasons for those codes the finger points to the most recently replaced component- the Bosch sensor. I bit the bullet and paid the high auto parts store price- end of problem. Bosch is normally a reliable brand- not this time.

I got a P0053 HO2S Heater Resistance (Bank 1, Sensor 1) code on my 2005 Silverado, so after looking it up in Google I found that code meant the upstream O2 sensor. My truck came with a Denso O2 sensor, but this Bosch sensor was a perfect fit and seems to work even better than the original part. My engine runs a touch smoother than it did before the old sensor burnt out, and as a nice touch Bosch even pre-greased the threads with heat resistant lubricant so it would install nicely and prevent it from rusting in place later. It's not like I couldn't do that myself, but it shows that Bosch really pays attention to the little things when it comes to their products.

Easy installation

I had this check engine light code on and off stating Bank1-Sensor1. Bought this sensor at an attractive price and fits like the original. My check engine light has not turned off yet, maybe eventually it will turn off by it self after a while w/ a longer drive. I hope.UPDATE: After about three days my my CHECK ENGINE LIGHT finally went off, so it worked! I raised my review from 3 to 5 stars . I was quoted in the Auto Parts store for $59. 99 for this a lot more compared to $35 here in Amazon.

Perfect fit for my right side bank 2 passenger side upstream and downstream replacements on my 2006 Chevy suburban 2500 8.1L. Don’t bother buying the 7/8” O2 sensor socket. Worthless. Get two 7/8” combination wrenches. One to use and other for a cheater wrench to break free. Sensors came pre anti seized, but recommend more on the threads. You will have to cut the old sensor plug off to use the box end of the wrench.
