The order below is the recommended one: first the codes that can cause the others. After each repair, clear the codes and check which ones come back.
Order of inspection
P0102 Mass or Volume Air Flow Circuit Low Input Medium
The P0102 code means the signal from the air flow sensor is lower than any operating condition can justify. Unlike P0101, which compares the reading with what is expected, here the value is outside the possible electrical range: there is usually a high resistance in the circuit, a very dirty sensor or a leak letting air in without being measured.
