Default CEL Codes: 15 and 21

I wrote this in the EG/EK forum but no one seems to want to help me out so ill write it here.

I was just crusing noramlly and my VTEC would come on like normal. Went to pick up a friend and while we were talking outside the car was still on (never turned off the car) and then we go and while in 2nd gear before VTEC it bogged. I think thats weird cause it never did that again, so i try VTEC again. Bogged. WTF?! No CEL or nothing but it still did that. So i pull over and turn off the car and turn it back on, boggs worst then before. I check the oil, still good. Then i check my ECU for any back codes or codes that arent showing but are there (incase if my CEL light is going out) and i found these 2.
15 Ignition output signal (i guess thats why it takes a while for my car to start)

21 VTEC spool solenoid valve (probably why im bogging)

Now the only thing i could think of thats throwing 21 is probably because my cam seal is broken, could that be throwing the code? But what exactly is 15 and how could i fix that? Thanks

Cliff notes for the lazy: How do i fix code 15 and 21?
