Modding in the permanently open position is completely harmless, though you should probably leave it unplugged.
To be clear, it would never close to restrict airflow other than the natural restriction it makes by being there. Regardless, it's not required. It'd be nice if someone machined a pipe to get rid of the sensor completely. I like the stock airbox, but this sensor is crap.

So, do I understand correctly that, if no vacuum is applied (as my case where the vacuum is disconnected on that side), the vane stays essentially open?
