Just had this issue. There is no sensor in the PS fluid reservoir I just found out (this was a surprise, I swear I get a code from the AC unit just when I fart!), so I let my reservoir run really low. I got an intermittment high pitched whine between 1000-2000 rpm. With the full reservoir, the noise has gone away (so far). I also have a drip from my reservoir supply pump pipe which needs fixing too!
