Default Check engine light on, code P105B

2017 Stingray with 21k miles and just noticed the check engine light steadily on, took it to O’Reillys to check the code that came back as P105B. Anyone had this happen before and approximate cost of repairs at the dealer?

Assuming it's a sensor issue and not a wiring issue, it'll be a couple hundred dollars plus the cost of the part. Of course the dealer rates vary significantly based on location and some dealers charge MSRP for the part, some are less, some are more. Best thing you can do is call them. "I need the driver's side front o2 sensor replaced, how much?"

Why take it to a dealer ??…if you take it to an general repair shop they will just change that part too because of a trouble code…a general repair shop will be cheaper…a video below of not what to tell them to replace.
