Does having a CEL for not having an air pump means the VTEC will not engage?

I was running the K-pro before and removed the air pump. I recently switched back to the OEM ECU and there is always a CEL because of the removed air pump. Does this mean my VTEC will not engage as long as the CEL is on?

Sorry if this is a stupid question.

 

Your vtec will still engage.

 

why not go and try it. but depending on code. that one should not keep you from enjoying vtec

 

I'm curious why you dropped the kpro? Especially after having to install all the related RSX sensors. It seems like a really worthwhile mod, especially on an early ap1.
