You need to connect a OBDCII ( computer code reader ) to your car to reset the code.
take it to AutoZone
They'll read the error code and reset it for free

Po101 code


Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. Check for air leaks on or around any intake pipework using a good spraying of carb cleaner, if the engine surges then that's the leak. Check wiring to Maf and if the inside is dirty, again use carb cleaner liberally...NOTE: do not use Wd40... If the code comes back, it may be necessary to replaced the mass air flow sensor.

Whath does "service engine soonmeans"


SERVICE ENGINE SOON and SERVICE ENGINE NOW are 2 amber warning lights pertaining to the vehicles computers.SERVICE SOON advises you of a problem, although not an emergency should be attended to promptly. Your technician can trace the problem by accessing fault codes through the climate control panel. SERVICE NOW indicates a more severe problem which will most likely precipitate a failure / breakdown. The CHANGE OIL LIGHT indicates by time and mileage is a separate light.
