My check engine light was on and it was giving a code of P0102 (Mass or Volume Air Flow Circuit Low Input). Then was told it was the Mass Air Flow Sensor needed replacing. So I replaced it and the check engine comes on and goes off like its suppose to. No trouble codes. I need to get it smogged but heard it needs to "recycle" first. How far does it need to be driven so I know its truly fixed?

Thanks

Readiness Monitors need to set. 8 of them, or the vehicle will fail Emissions Testing (depending on how strict the testing is).

Depending on driving habits, this can take a few days of driving. If you know what you are doing, you can set them in 20min or less.
