A friend removed the air pump because we installed the TKT power pulley kit from Pettit and I'm wondering if these error codes have anything to do with it or are they an entirely different issue.

Since all of these solenoids go into the Air Control Valve I'm not sure if just removing the Air Pump would generate them. These are the only solenoids that even go into the Air Control Valve. I didn't do the work myself.... could it be possible that the Air Control Valve was removed along with the Air Pump???

Inquiring minds want to know. USA all the way!
