Welcome to the forum!

Have a look at the attached bulletin. This is the Canadian version, but there is a US version...probably posted somewhere on the forum.
When you look at the title initially, it doesn't sound like your issue, but read the top of Page 3, section 1 and the first bullet. Some have complained about the valve being noisy, so this might be your issue and the bulletin would still apply to your vehicle.

Do you have any issues while driving?
If your boost sensor is bad, you will feel the rocking sensation felt while driving spiritedly noted in the service bulletin Sasnuke posted.
