Daaangggg! That bad? I saw this in the comments on the Boxter Engine Swap write up.
stephers Comments: I have a
2003 2.7 Boxster that has blown out the IMS bearing and the only altertanive engine is a
2.7 2000 engine. I have completed the update, put a new clutch in and installed everything into the car but I am getting one trouble code that I cannot get rid of. P0349 is the code " cam position sensor 2-open circuit " I have checked all the wiring and actual rotor, all is OK.. What can I do to fix this. A newer engine right now is just not an option where I am.
Followup from the Pelican Staff: Have you confirmed the signal it present at the DME? Since this a circuit code it is pretty cut and dry. Tee DME expects to see a certain amount of voltage at the Camshaft sensor wiring and does not. I would suggest: working at the DME, KOEO (key on egine OFF) backprobe camshaft sensor 1 and see what you have for voltage on all 3 wires. Should be something like, 5 volts, 0.1 volts and 5 or 0.1 on the other (depending on shutter position). Then compare those values with the sensor that is giving you the problem. Use this test to track down what wire(s) is open or shorted. -

The above gives me some hope considering he swapped his 2003 to a 2000 lol.
