    Got a check engine light with a P2601 error code this morning - Coolant Pump Control Circuit Range/Performance. Referenced here:

    P2601 Coolant Problem - Dealership replaced waterpump... help! | PriusChat

    What's the urgency to get this taken care of? Can it wait until after my 320 mile round-trip holiday this weekend? My mechanic and I haven't noticed anything unusual, just the error light and code. This was its first cold morning start in awhile, don't know if that had any affect...

    There is no urgency. This relates to the CHRS pump which runs only upon cold startup and engine shutdown.

    Thanks for the replies. This forum is awesome! (Although a little hard to search sometimes)
