Hello, so every 200 or so km i get this error P1429 "Permanent fault. Differential exhaust pressure signal. Coherence of the differential pressure when stopped" and i just clear it and it doesn't come back until after the aforementioned distance.
I decided to change the sensor and ordered one off of autodoc. Entered my model and engine type (607 2009 2.0 HDI 136 9D,9U), and this was the sensor it gave me

When it came time to mount, I went and checked some schematics and couldn't really tell where it was, then when I looked under the hood, I found it and it looks nothing like mine, also it's like 4 times the size. It's this one I think.

Does anyone have any idea if the one I ordered would work or not ? Can I just swap it out ? The connector seems to match

Check pin out and electrical plug size match up, the parts don't look all that different in the images.

Well pinouts and connector looks the same (3 pins in a straight line), only the sensor as i mentioned is 3-4 times smaller.
