The second cheapo little plastic rotor/magnet in the cam position sensor apparently has failed again in my 3.0 Vulcan at 126K. The original one failed about two years ago during a period of very cold weather (brittle fracture?). Explains the hi rep rate tapping I recently heard that has since gone away! Outside of the OBD II P340 code and the resulting check engine light, the car is running fine.
What function does the cam position sensor serve in this engine? I will be changing it as soon as I have time to get under the hood, but like I said the car is running fine w/o it. I'm assuming the engine managment system is using a default value for the sensors output while it's failed.
