Transfer Function of Pressure Sensor: Uout= (c1*pabs+c0).US Where, Uout = signal output voltage in V US = supply voltage in V pabs = absolute pressure in kPa c0 = -0.1/105 c1 = 0.85/105 kPa Characteristics of Pressure Sensor: Characteristics of Pressure Sensor with Supply Voltage of 5 Volts Characteristics of temperature Sensor: Resistance vs Temperature Characteristics Stand Alone Diagnosis of Sensor: 1. Give 5V Power Supply to the Sensor Supply pin and Ground to the Sensor Ground Pin 2. Keep the Sensor in a pressurized environment of 50 bar. 3. Measure the Voltage between the Sensor pressure Signal Pin and Ground, it should be 2.1 Volts approx. 4. Check the resistance between the Sensor Temperature signal pin and EMS ecu, @ Room temperature of 30 Degrees, it should be ~1080 Ohms.
