Sure, here are the steps to enable the profiler in CodeIgniter query profiling:

1. Open the CodeIgniter configuration file located at application/config/config.php.
2. Find the line that says $config['enable_query_strings'] and set it to TRUE.
3. Create a new controller method to activate the CodeIgniter profiler like this:

    public function enable_profiler() {
        $this->output->enable_profiler(TRUE);
    }
