Codes 170 And 173

On my 99 320e w/24k I am getting error codes 170 and 173. From what I have read so far the problem is a bad mass air flow sensor. Are there any other possible causes? Thank you in advance for your reply.

I would remove the MAF, clean it with electrical contact spray cleaner & re-install it.
Even if it solves the problem temporary, you proved a point.
