Can a demagnetized or dislocated magnet on the camshaft gear be repaired?
What is your question?
My 1992 Bonneville SE is stalling after 10 minutes or less then won't restart for about an hour. Initially it wouldn't put up a trouble code in the computer, but finally kept it running long enough to set up 2 codes. 31 and 41. The PNP switch has been bad ever since I owned the car, but the 41 code suggests the camshaft sensor circuit or cylinder select in the ECM. I am assuming it is the camshaft sensor since in the code reader manual, a 31 can also refer to the camshaft sensor circuit. By pulling the gear shift down to drive and increasing the RPMs, I got the car to keep running past the sputtering and it continued to run fine afterward until shut down and the check engine light appeared and revealed the codes. The engine would not restart until it had cooled down for about an hour. When it does this, I have checked and noted that there is no spark from any of the ignition coils until it has cooled. I have cooled the ignition coils with alcohol, but still they do not set off a spark until the engine itself has cooled. Any one else experience a problem similar to this and if so, what causes it. Engine runs great when running and has always been dependable until just 2 weeks ago when this problem surfaced.

I am going to try the crankshaft position sensor. Initially that is what I thought ft might be, but when it put out the codes for the camshaft sensor, I tested it and found that the ICM was not sending a message to terminal "A" on the sensor. I replaced the ICM today, and the same problematic condition still exists. I am going to do the crankshaft sensor either tomorrow or the next day. Thank you for your attention in this matter. I really appreciate the advice. I have not had much experience dealing with failed sensors, etc.and had hoped not to fall into the "learning experience" due to problems on my own vehicle. I figure I will hit and miss a few times and if I don't get it, I will seek a different vehicle rather than go broke replacing parts to chase the "unknown."
