I didn't have an engine light on either but my app was still showing pending and fault codes for the MAF, I had code P0101.
I had a bit of stuttering after I cleaned the MAF so make sure you drive enough and mixed driving helps too, spirited and stop n' go will help everything calibrate again.
And if this doesn't work you're only out $10. But if it does work, you save $150.
