It may mean the catalytic converter has gone bad. Can you post the actual code?

64,350

Do not know if catalytic converter cleaner works but my check engine light came on saying bank one oxygen sensor replaced sensor and light still came on saying bank one oxygen sensor so I thought I had to replace converter but before doing that started using 92 octane from wawa and 93 octane from Exxon was using 87 octane since I owned vehicle for 10 years took about 10 tank fulls and light coming and going off 5 times but light is off now and has not been on since.
