What does 'GPF is full, please increase speed' mean?

GPF is full, please increase speed refers to the gasoline particulate filter being clogged. GPF is a ceramic filter installed in the gasoline engine's emission system, which captures particulate emissions before they enter the atmosphere. The main function of the GPF gasoline particulate filter is to reduce particulates. When the indicator light in the car comes on, it means that the particulates accumulated in the GPF have reached a level that requires cleaning. If the indicator light is green, the situation is relatively better, and you can drive more on highways to allow the GPF to self-clean the deposited particulates. If the light is yellow, the solution is to increase the exhaust temperature to burn off the carbon deposits.
