Low-Pressure Sensor Configuration (63LS)

The low pressure sensor consists of the circuit shown in the figure below. If DC5V is applied between the red and the black
wires, voltage corresponding to the pressure between the white and the black wires will be output, and the value of this voltage
will be converted by the microcomputer. The output voltage is 0.173V per 0.098MPa [14psi].
The pressure sensor on the body side is designed to connect to the connector. The connector pin number on the body side
is different from that on the control board side.
