I’ve removed a DPF sensor from a scrapped 2010 Fabia (to use as a pressure sensor on an oscilloscope). But I don’t have access to a wiring diagram. I’m sure that Pins 1 and 3 are the 5V power and ground but I don’t know which way round. Pin 3 wire is white (ground, I expect) and Pin 1 is red/light green (+5V?). I’m reluctant to connect up in case I blow the sensor.

Most grateful to anyone who can check the wiring diagram for me.
