<p>PURPOSE:To ensure the reliability of a detector by enhancing the detection accuracy of the flow rate of intake air even when intake air pulsation containing a back flow component is generated. CONSTITUTION:An intake air passage 13 is divided into an intake air passage 13a permitting only forward flow to pass and an intake air passage 13b permitting only back flow to pass by a central partition wall 21 and shield walls 22, 23 and the temp.-sensitive resistor RH1 incorporated in a circuit outputting only forward direction output is arranged to the intake air passage 13a and the temp.-sensitive resistor RH2 incorporated in a circuit outputting only reverse direction output is arranged to the intake air passage 13b.</p> |
