Hey Russel,
Very nice !
It's weird that the ECM didn't throw you a DTC31...must have been so confused by the non-working sensor that it didn't know how to react (the failure was probably not landing into the "missing pulses" category or "extra pulses" one...interesting.
So, if I'm not wrong, you will face the second issue. The camshaft sensor lands into the "hard to find parts" section. No longer manufactured or stored.
Original PNs were : 10137658 / 10137658 / 213-141
I came across the following threads about modifying an aftermarket one.

Phil (Jagdpanzer) seems to be able to make some based on aftermaket parts : he provided his email in the above thread :

Latest requests were done in June this year, so it should be feasible to get one I guess.
