P2A01 Oxygen Sensor - Is this common?

[rusty813]

Bought my vehicle used with 75k miles, and now had 92k miles. Have check engine light with p2a01, need to replace oxygen sensor. Previous owner sold me a car with hidden problems, and has a clean title. I am reading that cylinder head or leaking gasket could cause this. I am curious if it's common for o2 censor to go bad, and is it possible to make a bad engine to run for 1 or 2 years?

Had o2 sensor last go in 05 Mustang 4.0L.... rare to go. If you don't have other issues then likely a fluke. These cars dont have gasket issues.

Always can have pressure test done if you want. Pinging or oil in coolant (or vice versa) is a problem. I would fix it and not worry.

I did a quick search on O2 and found that there are several threads on the O2 sensor but yours is the only one with the P2A01 code. The others have varying codes. P2A01 O2 Sensor Circuit Range/Performance Bank 1 Sensor 2
