Hey Everyone,
I have been searching all of these treads to figure out how to fix my power steering. I found the old threads on how to clean the parts and I did that. But I think the pressure sensor is bad. I tried to clean it out also and my steering still turns hard. When I hit 60MPH my steering wheel shakes also.
Other than that I got this car for $1200 and it runs so good still.

Scan for engine codes.
Is the pump spinning smoothly, and PS reservoir full of clean oil? Inspect all of the hoses.
Parts on Rockauto. I replaced power steering pump and high pressure line on my Q45 last year.

Welcome to the forum!
The FGY33 is a great platform once properly sorted out. Very reliable and most things not too difficult to work on.
Dan offers good advice, unlikely your shake at 60 MPH is related to the hydraulic assist function.
Why do you think pressure sensor is bad?
How do you know you are actually building sufficient system pressure?
