Remove it and clean with some carb cleaner and a Q tip. Be careful with it so you don't do any damage. 9 of 10 times this will get you running again! Since signal from there is variable low voltage, you cant really bypass it!

SOURCE: Mass Air Flow problem
The M.A.S. is in the top of the metal tube between the air filter box and the intake manifold. It will have a wire connected to it and it is held in by 2 screws. This is an easy replacement and should take no more than 5 to 10 minutes, assuming you are taking your time.

yes your right. it is a low circuit input code for a mass air flow sensor. you can try taking the mass air off and cleaning it good. sometimes it will help but normally they are just bad.
