Prius has been sitting in the garage for several weeks -- it is bone-chilling cold here. I went out to start it up and begin packing it. Noticed "Check Engine Light." Connected my OBD-II scanner. Got Code P261B which indicates a "Coolant Pump 'B' Control Circuit Range/Performance" issue, Cleared the code. Turned off the ICE. Restarted. Code has not returned with engine running for an hour. I was planning on a 2,000 mile trip starting today. Would you be worried or is this a common one-off? Thanks!
I would be perfectly confident to make a coast-to-coast road trip. There is always some minor roll-of-the-dice chance that any roadtrip could result in a breakdown. Such is life.
While a breakdown is always possible, I think the OP was concerned about the engine coolant code that got thrown (check engine). The question is given the environment (extreme cold, car sitting for several weeks), code gets thrown, gets cleared, and doesn't return in an hour, whether the code was probably a glitch or is a probably legit and something to be worried about on his trip. I don't know the answer to that, but I bet someone here does.
