Opel vivaro P0100 code (MAF sensor replacement)

Removed the check engine light by replacing the mass airflow sensor in my opel vivaro. While I was in there I also put in a new air filter. Not shown: I first tried cleaning the contacts and the sensoritself with electronics cleaner. That didn&work. So I used a multi meter to check if the sensor was getting power, and it was. The only solution was to get a new sensor. Problem fixed in about 8 minutes.
