So I went in for a car inspection, and my car did not pass. They said one of my O2 sensors was no good, and they gave me the error code they got (P0134: O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)). They quoted me $365.

Took me about 5 minutes to find a 5 minute video that showed that I could change the sensor myself easily. I looked online at a few sites and for my Honda CR-V 2003, two sensors came up frequently, a Bosch and a Denso. I called the Autozones in the area and there were no Denso available, but one close by had a Bosch so I went and picked it up and installed it quite easily.

However, a friend told me about this site. Curious, I looked around about O2 sensors on these forums, and I found that many past posts recommended the Denso over Bosch O2 sensors. Upon inspecting my old sensor, I also found that it was a Denso.

Did I make a tragic mistake by getting the Bosch sensor? Or is this nit picky? Is there any way for me to test whether this Bosch sensor may cause problems in the future?

Thank you Honda Techies

Bosch are good for 1-2 yrs depending on gas and maintainence of vehicle as for denso itll last forever.... No but really denso makes some serious parts

Denso is superior to bosch IMO. I don't think you made a tragic mistake. The worst thing that will happen is the light will come back on.

i have installed bosch o2 sensors and right out of the box they are no good.
NGK has a side company called NTK o2 sensors and they are excellent quality. I personally say stick with denso or NTK only and of course oem honda lol.
