Techinical help please - what does this bit do?

Hi, I'm a new owner of a 156 2.4JTD (the 10v version) and have a problem with my injection system warning light (it stays on). At the back of the engine directly above the electrical plug that fits into the centre of the common rail is another electrical plug (it's the one in the centre of the picture). It was finding this loose and making the mistake of plugging it in with the engine running that caused the fault light to come on. It now stays on regardless of whether the plug is connected or not.

Can anyone tell me what this plug is for so I can get a rough idea what might have gone wrong?

Thank you.

Well if its the plug facing up in the picture that is your manifold pressure sensor and the one below that is the diesel pressure sensor.
