Been home about 3 hours. Just walked out in the garage and I heard a low humming sound under and back of CRV. Sounded like a small motor or fan would sound. Started the car and it stopped. Any ideas?
I've never actually heard the sound.. but I have seen it activate on my bluetooth battery monitor when I upload the data log periodically as it will draw notable current while active and I can easily see it on the time-data graph. Looks like it normally triggers about 5 hours +/- after vehicle shutdown.. and it will not do it all the time. If I recall correctly, Honda claims it is based on the current level of fuel in the tank.Thanks for that info. I noticed the same sound a few weeks ago and couldn't figure out what it was.
