    So,
    Yesterday I get check engine light on and truck is running fine. It was raining a lot so maybe that caused some issue.
    Today I checked codes on Ta and I got this 2:
    1) p042000 - catalyst system efficiency below threshold
    2) p200200 - dpf efficiency below threshold
    I dont see any issues through after treatment diagnostics and truck is running good.
    Anybody know anything how urgent is to get to some shop with this?
    Thanks

    Is the light on? Like you said it could be environment at the time.
    If it went off no harm, no foul.
    If it's still on, it should be fixed yes. Not urgent, but next home time for sure.
