Owner put a scanner on the car and produced no codes other than scanner stated all cylinder timings were off. (I wish I was there)

Hi Pat,
Interesting scanner. My scanner only puts out error codes and keeps its thoughts to itself
I've looked at the signal from a crank position sensor on a scope. It was a single output type and put out a 5 volt square wave. On a voltmeter, it measured less that 5 on the AC scale because of the square wave shape I'm almost certain.
Instead of nicking the wires, it is sometimes easier to push a straight pin (from a sewing kit) down beside the wire into the connector and measuring from there. In the books, they call it back probing but don't recomment it for use at the PCM connectors. Guess there is a chance of screwing up the connector and would have to change out the whole harness.
Sometimes just unplugging and replugging connectors will clear up some weak contact problems. You can try this at the PCM.
Does anyone know how much off the compression would be if the timing chain slipped one notch?
Keep us posted Pat. I think we are all scratching our heads with you.
Best regards,
