Hi, trying to get my car back up and running before MOT next week and having trouble locating the crankshaft position sensor. I had 3 fault codes, leading to cam position sensor (now replaced), bank 3 and crankshaft position sensor. But I cannot pin down exactly which one is the correct sensor. Appreciate any help. Have attached a pic of what I 'thought' it was but now think thats a knock sensor.

You'll need to tell us which type of engine your Fabia has, there are several options.

No idea what 'bank 3' might mean unless it's something referring to cylinder 3?

Guessing it might be one of the 3-cylinder 1.2L variants?

Does it start and run, or not?
