Sensors and Actua<strong>to</strong>rsEmployed in OBD <strong>II</strong><strong>Diagnostics</strong>The display device converts the signal from signal processorin<strong>to</strong> a readable quantity.The sensor converts energy from the formof the measurement variable <strong>to</strong> an electrical signal. An idealanalog sensor generates an output voltage which isproportional <strong>to</strong> the quantity being measured:v 0 = Kq 0 , where K is the sensor calibration constant, v 0 isvoltage, and q 0 is the measured physical quantity, such astemperature, etc.
