I realized that I misread my phone earlier as I was inspecting the SAP valve. The monitors that are not ready are Catalyst, O2 Heater, and Evap.
I just checked and the o2 heater fuse in the dme tray is not blown. Still no codes or SES light and I have about 700 miles on the car of me trying to set these monitors.
I really have no idea why the secondary air and o2 sensor monitors suddenly switched to ready after I had given up on drive cycles
