Question about 2000 Buick LeSabre
I can tell you with certainty that it was not the O2 sensor. They tell you to replace what it shows up and that is not the case when reading these codes. Unfortunately, since it is an electrical component, you cannot return it. Once installed, you have it period.
Now, back to the problem....if you have the same code then there is a really good possiblity that the wires or the connector to the CMP (camshaft position sensor) has a break in it. Either it is melted somewhere in the harness or the connector is faulty.
Only way to know this is to inspect the wires or take the vehicle to the shop for a diagnostic where they can connect to the harness to shoot an electrical signal through it to see if the harness is damaged.
$80-90 right off the bat to find out, unless you have a friend in a garage that has the tester.
Hope this helps!
