Best to use a scanner to check for the issue, but in most cases with your issue is the water pressure sensor on the power steering cooler

And motor serial numbers are best

IAC would be the no1 suspect. Exactly this happened to mine.

Edit. So just read again. Forget the above. Mine didn’t constant beep above 3000rpm. Get it plugged in and see. A constant beep isn’t good. Check your gear oil header tank and all pressures and temperatures too of course
