I tested the codes and it blinks 111 111 1 212 212 what is that one in the middel between codes?? its throwing me off? Does it repeat the codes twice????

With Key on engine running im getting 311,,314

Which is
311 AIR system inoperative during KOER (Bank number 1 with dual heated oxygen sensors)

314 AIR system inoperative during KOER (Bank number 2 with dual heated oxygen sensors)

What does that mean is wrong?
