low oil level light

[Downbound]

2012 outback 3.6. 158,000 km's The low oil light came on 3000 km's after an oil change. The dip stick was only down about 1/2. Topped it up but the oil light never went off. I know it sometimes takes awhile for the light to go off but it was on for 2 days.

Found this fix on Utube and it worked like a charm. 

Does anybody have any idea why it worked? Does it reset the sensors? 

Thanks
