BOSCH 15200 Premium OE Fitment Oxygen Sensor - Compatible with Select Cadillac Escalade, ESV, EXT; Chevrolet Avalanche, Silverado, Suburban, Tahoe; GMC Sierra, Yukon, Yukon XL

I have been fight high short term and long term trim levels and found the O2 sensor had no reporting voltage. Everything online said it is not the O2 sensor, but it was. Installed super easy and truck runs like a new truck! Way cheaper than the auto parts store too!

this part perfectly , thank you

2012 GMC 5.3 Ordered Bosch 15200, box was correct- part inside was an obsolete FL00HL00319. This part will fit, but will give check engine light due to not being compatible with vehicle ECM. Bosch 15200 part should be stamped FL00HL0349. Buyer beware and verify part numbers before using.

I figured shoot why not just a few bucks more for the brand name ones figured they would be much better but I Will not buy again will go back to the off brand I am used to as one of these brand name one’s installed and started the truck ran great till it went into closed loop and started using the o2 for fueling and truck set a check engine light calling for +40%fuel needed and started back firing after hooking up my scan tool and noticed bank 1 sensor 1 was very slow reacting and that bank 2 sensor 1 was maxing out causing long term fuel trim maxed out as well as short terms caused mas over fueling and back firing. Again will not buy again.

Got rid of codes.

Easy to install on my 2009 Chevy 1500 4wd.

Good fit, easy to install.

So I installed this into my vehicle but the one it was replacing had a little bit more narrow body. For that reason, I had to have both of the oxygen sensor socket types. The more narrow one to remove and the wider one to install. I wish I had known ahead of time as it would have saved me a trip to the auto parts store.

Sensor appears to be great quality but the parameters that the sensor operates is not compatible with the ecm. I have also heard from other guys i have spoke to they have had the same issues with bosch sensors and their compatability with gm products. Instapped and removed so coupd not be returned. Buy a denso if you need an o2 sensor.
