    Hello, last week my check engine light came on, I have been having no problems with my 2010 Prius with over 246xxx miles on it. I took it to Autozone and they used the diagnostic plug in tool and it stated three P0240 codes, catalytic converter and two o2 sensors were needed.
    Today my check engine light is off and I have not had anything done to remedy the problem yet. I am taking it to my mechanic who performs my routine oil changes to have him double check this issue.
    Is anyone familiar with this issue? I have only replaced my spark plugs last year but had no other major work done on it and don't want to let a small problem cause a major issue.
    Thanks in advance for any advice.

    Replacing the cat is common with those miles
