Engine system service urgent - P0121

Hi,

Getting this code P0121 and Message "Engine system service urgent". It only comes when the Engine is hot or I drove over 50KM. If engine is cold and start in the morning, no such code until I reach my destination and start immediately. Google tells its about "TPS/Pedal"

Else no issues on drive - Same as before. Anyone can help to the right direction and my main concern is why it only comes when engine is warm and only starting. Plus some time it comes and some times not.

Car: Volvo s80 1999 2.9 Non Turbo with 130K miles on it.
Kindly advise.
