Unknown afm wire shielding/earth?

[LINK17]

Hello All,

Currently dealing with very frustrating rb20det intermittent power loss issue. It is the afm/plug/white wire second from the left when looking towards firewall.

I know this cos every time the car stutters I pull over, jiggle it and its fine for a while/day/week.

I had some time today so peeled back the wire shroud and came across this (Pls see pic). I have read the manual/wiring diagrams but not sure why it's externally earthed and is this the way it should be? How do i connect a replacement afm plug? Wire looks oem- has some letters A S S S H? On them?

Any input would be greatly appreciated.

The  diagram I have for a S1 R33 says

A not connected

B Signal

C 12v ground

D Signal Ground

E 12v power

Yup so the wire is a ground either way? Why would it be shielded?

Um....is it not that the signal and signal earth are both inside the shielding? In which case, why be surprised that they are shielded. The voltage between those wires can be as low as 1V, so it makes sense to protect them from RFI. The shield should be earthed at the other end (ie, it should only be earthed at one end).
