ABSTRACT:
A mass air flow sensor calibration air flow stand is tested during production by substituting a nozzle supplying a predetermined amount of air flow for a mass air flow sensor in the production line. The calibration air flow stand is supplied air from the nozzle. If the calibration air flow stand is operating properly the flow in the air flow stand is the same as the predetermined amount of air flow.
