Can a loose gas cap cause an O2 sensor to fail?

The codes for loose gas cap and O2 sensor problems are different and there is no interaction between the two. O2 sensors do get tired and 95000 miles is definitely in the range where failure is plausible. Most cars have two O2 sensors. It’s likely that the one replaced in 2008 is not the one that is giving you trouble now.

Can a p03xx code fault the O2 sensor?

Ask any decent mechanic, and they will tell you that when they get a P03XX code that faults the O2 sensor, they still check the freeze frame data and often see anomolies in other systems that lead them away from the O2 sensor as the culprit.

What does the p0151 code mean on a Chevy?
