Question check engine light

I own a 1990 Buick LeSabre with a 3.8L V6 engine. I've got a check engine light on with a code of 41. Of the 2 things that can be fixed on the car, the Cam position sensor and the Ignition module, both have been replaced. I disconnected teh battery after each part was replaced and still have the code in the computer. The car runs just fine with no stuttering under acceleration or hesitation. The light popped on as I was passing another vehicle. My car does have over 200,000 miles on it, but runs like a top. Any help/advice would be helpful. Thank you.

Is there a magnet on the shaft that the cam sensor needs? Is that magnet OK?

Then also check the wiring and connectors to all the above.

One *nasty* problem with connectors is someone has shoved in a too large prong for testing, then the female terminal no longer grips the male terminal as tightly as it should.

The electrical cables would go all the way to the engine computer and there would be another connector there...

If you are a computer type, you may be able to get WinALDL free and see live data (what the engine computer is seeing). Get that here...
