ABS is not part of the engine. You may have a brake or other problem light that you didn't notice.

I probably have dirty MAFs as my car sometimes goes into limp mode when I first start her up with no cel light. Every few months, I will get the cel light and when I hook up my obd ii scanner, it gives me the MAF code, which I’ll clear out. So no, a cel light will not always come on.
