I’ve bought a DPF sensor on ebay - part number 076 906 051A. It’s to be used as an exhaust pressure pulse sensor for a PicoScope. Problem is I can’t find anything on the Internet to tell me which pin is power and which is ground. Going off similar vacuum sensors I’ve used, I could make an educated guess - and ruin the sensor if I’m wrong.
i’m fairly sure it’s the outer pins that are power and ground with the middle pin being the signal pin. So, looking into the end of the sensor with the locking pip upwards and the rounded edge on the left, I see 3 pins marked 1,2 and 3.
My guess is Pin 1 is ground and Pin 3 is +5V. I’d be most grateful to know if that’s right.
Also, I can’t identify the connector - I know it’s not Superseal, though - so I figured I could get one from a scrapyard. I assume the DPF sensor is fairly accessible in the engine bay so I could snip off the connector?
Many thanks.
