Whine and buzz under the hood while in Ready

richard schumacher · 01-31-2009, 07:48 PM

Before today I'd never listened under the hood with the car Ready. There's a distinct whine and buzz apparently coming from the inverter, audible only when the engine is not running. Is This Normal? All the coolant tanks are full.

The inverter does whine.

You will hear the inverter and also the coolant pump

The coolant pump is very quiet, and the inverter doesn't make
a whole lot of noise when the car isn't moving.

You're most likely hearing the throttle motor on the front of
the engine.

My 07's Inverter is real loud just sitting in Ready first thing in the morning. Really loud.

I had a whine under the bonnet until I let my wife ride in the cabin with me, now I have a a whine inside the car.

It's a hastle that I can't tow a trailer with my Prius or I could fix the whine.

Oddly enough, the electric throttle on my Prius is *very* quiet

However, the electric throttle on my FJ does make a loud whine. I found this out last fall when I decided to clean the throttle body and MAF. I had a neighbor kid keep the gas pedal floored while I sprayed the gunk out of the TB, and it really does make a lot of racket, no matter at full throttle or idle setting

I sure hope you're not suggesting she is

Or you'll be sleeping on the couch for the rest of your natural life
