phantom clarinet toot

I wonder if it sounds similar to or even has the same cause as the brake barking/honk on the 2nd gen? (http://priuschat.com/forums/gen-ii-prius-technical-discussion/19051-my-brakes-barking-me.html) I hear the "honk" every now and then on my 2nd gen...

 

Will have to listen out while I do my pre-flight checks

 

B or B-flat... in which register?

 

Are you sure it's not a Concert A? Maybe your Prius needs a tune up.

You might want to stop the lunches at Taco Bell.

 

You knew the replies were going to be like this... Anyway I went out and tried it a couple of times (unusually without kids) and I hear some relays clicking, sometimes the rumble of a pump, a beep from the Nav and then the Nav DVD seeking a bunch of times and then the ICE starting up. I don't hear anything that I would describe as a "toot". Does it happen every time? Could it be the CD player or Nav seeking? Can you go try another car at the local dealer? I had a loaner for a couple of days which was great since I could verify that all the things my Gen III does seem to be normal, or at least not confined to my car.

 

Fuel system dealing with air/vapour pressure? Sometimes those valves will emit noises, and every one is different. I know the GIII has a convoluted system to control emissions as it doesn't have the bladder.

Sometimes Pearl emits strange noises when the fuel system changes state (car on/off cycle).

 

You obviously, unknowingly got the Zamfir upgrade.

 

could it be the climate control system? like a vent purging/opening? I've heard it too, and thought it was coming from the underdash area like where air vents would be located.

 

Since you mentioned it happens when it's warm, and finman suggested the climate system..

If you switch to recirculation in the GenII, it makes an odd sound that typically can only be heard stopped with engine off and windows up. I wouldn't personally call it a clarinet sound, but it's close enough. It lasts for about 1-2 seconds.

 

Perhaps there's a jazz pixie trapped behind the dash?

 

I've heard this too. But in my case, it sounds more like an oboe.

 

I once spent an hour at four in the morning looking for the source of a beep around the house. I thought it was the alarm system or a smoke detector. Turned out to be a low cell phone. I would like to make a list of everything we own these days that beeps:

Cell phone
Microwave oven
Clock
Computer
Smoke detector
Watch
Bread machine
Car (many beeps!)
Answering machine
Carbon monoxide detector
Door bell
Cordless phone
Digital thermometer

I'm sure I'm missing a lot. Any more?

 

Wow! That was certainly a twist. I don't think anyone was going to help you find that. At least the exercise of trying to explain it to others helped you figure it out!

 

Rice Cooker

Roomba®
CPAP :yawn:
Uninterpretable Power Supply (UPS)

 

Glad you uncovered it. The next step would have been to provide gps co ordinates along with some map locations and pictures showing exactly where the toot occurs and try to recreate it. The temperature and relative humidity would also help. Thanks
