pump or humming sound - Toyota Nation Forum : Toyota Car and Truck Forums

ok, last night I went into the garage to get something and heard a strange noise coming from my 09 Sport. The vehicle was off and since about 5pm and it was 9pm when I heard this noise. It sounded like a pump making a sort of humming sound. The best sound I can relate it to is a bilge pump in a boat. The sound lasted for about 1 minute and was coming from, roughly, the middle of the Sport in between the 2 back doors. Before I could pinpoint the location it stopped.

Has anyone experienced this or a similar sound before?
Thanks!

No problem, it's easy enough to do because the search feature isn't the best in the world.

BTW (to everyone), I'll add a link in the Common Problems & Solutions sticky to the linked thread quoted above since this is a frequently asked question.
