Help! Fault Code!!

[TUX182]

I got this fault code on my car, does anyone know what I should be looking at?

Thanks for looking.

P0101....Mass or Volume Air Flow Circuit Range/Performance Problem

 

[Sean6545]

Is it bringing a warning light on?

 

[ScottyD]

erase it and see if it comes back after a run.

Mass Air flow sensor by the looks of things?

 

[TUX182]

No warning light...

Yes I may erase it and test again.... where is the mass airflow sensor??
