A little info here.... I have a '91 Olds Regency Elite 3800..... I was getting a code 42 and discovered a had several frayed and broken wires on the electrical connection to the ECM..... I replaced the ECM connector and spliced all the wires one at a time...... after I was done I started getting a code 41 (CAM sensor) that was not showing when I got the code 42........ Now I'm wondering if I have a wire issue..... OR a magnet issue on the Cam gear off and it'* just a coincidence? What do I need to check now.... I know I could take cam sensor off and check...... but I'm wondering since I just spliced all the wires.... hmm? Was one not connected completely..... which one do I check........

I'd trace the cam sensor wires back from the sensor to the PCM and see if you can find anything.

I have continuity on the 3 wires....2 to the ECM and the middle one to the crank sensor..... I used a camera to see the cam interrupter magnet and it is there on the cam gear and not broken off...... I even got a brand new cam sensor and put it on to little avail......... now what?

Hmmm . . . possibly the ECM then. I'll ponder this one for a while. Maybe somebody will chime in with another idea.

A thought: Is the battery in good shape and alternator charging well? Low voltage would cause weirdness.

Brand new ECM.....going to switch it out with another ECM today "just to see"........

Good continuity there...... still no luck.

. . . ?

The battery is brand new just a couple of weeks ago, and the alternator was changed about a year ago.

What caused the frayed wires? . . . and how many were frayed?

Do you have a list of which wires were damaged?

Age..car is 30 years old....nothing else caused fraying.
