The gear shift sensor doesn't think you're in Park is the only thing I can find as well. When do you see this code?
This leads more credence to the gear shift position sensor being at least out of alignment as this is the only time an automatic will warn you about not being in Park.I believe mine was produced in South Korea or Brazil, and is like the one in US. I get codes not text errors messages.
I get the error when I shut down the engine. I get no errors while driving and I have no other issues.
