Claim Text:
1. A mass air flow sensor comprising: at least one semiconductor device operating as a temperature sensor outside of a Wheatstone bridge providing an output to a digital processor; a hot wire providing an output related to a mass air flow past the hot wire, said output operably coupled to an engine control module (ECM) when installed in a vehicle; wherein output of the digital processor affects the output from the hot wire; wherein the output directed to the ECM is treated by the processor upon step increases of temperature prior to being sent to the ECM; and wherein upon receiving a digital step increase in the temperature the output is set by the digital processor to eliminate ripple effects by setting the output to one of (a) a calculated output based on temperature before the step increase for a predetermined time, and; (b) an anticipated output on a predetermined mass air flow curve.
