特徴とするクランク角基準信号の信号処理回路。 A crank angle sensor that detects the angle of the crankshaft of an internal combustion engine is connected to a control unit via a connector, and the crank angle sensor turns on and off based on a crankshaft reference position detection signal generated from the sensor section. The crank angle reference signal has a switch means, and when the switch means is turned off, a voltage from a power source for forming a reference signal is input to a reference signal determining section in the control unit, thereby determining that the reference signal has been generated. A signal processing circuit for a crank angle reference signal, characterized in that the power source is connected to the switch means within the crank angle sensor.
