hey i was pulling codes and got a code 314 AIR system inoperative during KOER (Bank number 2 with dual heated oxygen sensors). I also pulled code 332 insufficient egr opening detected. are these two related and what does the 314 code mean.

 

Check your vacuum lines for leaks and proper routing. Any leaks or misrouted vacuum lines could set both of these codes.

 

thanks for your reply, i will check the vac lines, i only know a little about there proper placement, anyone know of where a good diagram might be, i have a haynes manual but i don't see such a diagram.

 

There should be a vacuume diagram under your some where. Unless it was removed.
