Check VSC Error

[rahulbala]

Engine check ON, Check VSC in the display
I connected to OBD scanner and below are the errors
P101 MAF circuit range/performance
P0172, P0175, system too rich
P2241 O2 sensor pumping current low

i cleaned the MAF sensor and yet the issue wouldn’t go. Please suggest possible fix. I had the issue but went off in a couple of hours now it returned and won’t go.
