Icon6 Check Engine Light, ECU error (b16a)

Hi guys, I am new to the forum and this is my first post. I bought a 1990 CRX with this week a b16a in it. I had a 1985 CRX HF and recently sold it to upgrade to the new CRX. I am not that great with cars, I am trying to learn the basics. The problem im having in my new CRX is that it isn't hitting vtec. I have a check engine light that stays on. So I checked the ecu and recorded this video of the error code. Can you guys help me diagnose the problem?
Thanks before hand for putting up with my noobness.
-Tony

Would getting a vtec controller eliminate me from having to get the pressure switch?

well sure, but don't do that. vtec controllers are poop. troubleshoot the code and fix it. you will make more power and be more reliable if you let the ecu control vtec and adjust fuel trims like its supposed to.

Thank you sir. It's just that I have a friend that has an apexi vtec controller brand new in the box that he is gonna give me today... So its gonna save me 25 buck on the vtec pressure switch. That 25 dollars I saved I can use on seatbelt connectors. The seatbelt on the drivers side doesn't connect at all.

Hi guys...

Saw posts on B16A Problem.

FYI, I've just fitted a B16A in my EG8. I have and engine check light after a few while driving. However, sometimes it lights up and sometimes it does not.

Through the previous post (Thanks guys) I've checked the CEL message. Funny thing is, I can't really count it.

This is the error blink that I've recorded. My B16A Problem - YouTube

Hope you guys can help a newbies like me.
