New MPX5100DP no Vout

I've got a new MPX5100DP, which I connected to an Arduino, as follows:

pin 1: Vout to A0 on Arduino (analog in)

pin 2: ground on Arduino ground

pin 3: Vcc on Arduino 5V


This simple code:

#define MPX5100_PIN A0 // MPX5100DP sensor pin

void setup() {

  pinMode(MPX5100_PIN, INPUT);




void loop() {

  unsigned int pressureSensorValue;

  pressureSensorValue = analogRead(MPX5100_PIN);

  Serial.print("Pressure value.....: ");




... does not produce any other value than 1017.


How can I check, whether this sensor is actually functioning?
