MAF test, got over voltage reading

Refer to the test here:

My reading is turn the key to ignition without starting - 1 Volt

Start the car - 1.7 Volt

Give a bit throttle, jump to 2 Volt

Sounds like not a good MAF reading right? Besides, I have no got on code but hesitation.

I would try cleaning the MAF (with MAF cleaner only) first.

Also, clean the throttle body with a throttle body cleaner.

If that does not improve it then replace the MAF.

I have cleaned both but not helping, 1 day after clean the MAF and I got P0175 with CEL, wipe the code out and I dont have it come back anymore.

Thats why I gonna try to test the MAF on voltage side.
