I wanted to thank Theodore for this solution posted. In my case mine was unplugged and this article lead me to find that, plug it back in and get back to no codes. With it unplugged I got three codes 279D Power Management close circuit current violation (not sure this is caused by the hose unplugged because car sat during the stay home order), 2739 Secundary air mini-hfm electr. Diagnostics, and 27C5 Secundary air mini hfm plausibility. I could not pass smog until I figured this out so it was great to not have to spend a ton of time messing with this.
