Since nothing else can have the effect consciousness has, it can be defined by its effect. In other words, consciousness is whatever has that effect.
This is essentially behaviorism, which is now considered outdated and has largely been replaced by functionalism.
Consciousness is the result of many complicated processes working together in the brain. Even if you could create the function f(x) which has the same output as a human, it wouldn’t have the same structural organization that gives rise to that output: it would just be a giant lookup table. Consciousness is the result of all that structural organization.
The function f(x) with the same output as a human wouldn’t be a zombie, because it’s not physically identical to the human. It’s just a summary of the human’s behavior without the actual process that generates the behavior, and it’s the process that creates consciousness.
