The utility model discloses an inductance type electronic throttle sensor control system, which belongs to the technical field of throttle control systems, solves the problems of narrow application range, unstable circuit and high cost in the prior art, and comprises a power supply input end, a branch end I of the power supply input end is grounded after being connected with a capacitor C3, and a branch end II of the power supply input end is connected with an emitting electrode of a PNP tube I; the base electrode of the first PNP tube is connected with a resistor R4 and then is connected with the oscillating circuit, and a first branch end of the collector electrode of the first PNP tube is connected with an integrating circuit. According to the utility model, the resistor is connected in series on the inductor, the voltage drop of the variable current on the resistor is reduced, and the variable current is reversely amplified by the operational amplifier, so that the variable direct-current voltage acts on
