Clean MAF sensor.... or replace?

There are alot of reasons for sensors to throw codes and typically
they are NOT due to faulty sensors, they are due to intake leaks which
cause the sensors to report incorrect air volumes.
the other reason is dirty sensors, the MAFs can be removed from the wheel well
without jacking up the car, it takes some finesse and the exact angle to slip them out
but I did it and cleaned them. I used a tiny alan wrench and slowly removed the 3 screws.

I'd just reset it and keep going. I get them all the time running the interstate. I also took off the little high water intakes from the front of the air filters so it's easier to get the unbalanced airflow codes. If I drive it around town a couple trips they'll reset on their own. I really need to pull the nose off and connect the filter boxes together with some 3" dryer hose behind the filters. PITA

Dirty MAFs will report the incorrect amount of air (underreport) this is measurable and common.
if you add that with incorrect or dirty filters, and/or intake leaks you will end up with a check engine light.
A dirty MAF is not typically visually dirty to naked eye, also there are multiple sensor wires in our XKR MAFs
one wire is visible the other 2 are not visible and internal to the sensor, you must spray out all directions.
