What does af memory mean?

The mixed air autofocus memory means:

Citroen C4L reported P2 177 gas mixture adjustment adaptive fault. This fault is to clean the throttle first, then match the throttle, check whether there is air leakage, check whether the low-pressure oil pump is 5 bar, see if there is gasoline in the carbon tank, check whether the solenoid valve of the carbon tank is broken, and measure the cylinder pressure. This failure is very difficult.
