I agree it should be related to the sensor. That was the issue for another guy here a few weeks ago.

Do you need any info to help look into it?

You needed 3 quarts of oil but it took 6.75 quarts? Did you add 6.5 more quarts to fill it? You put in/added more than the engine is supposed to hold? Is that correct in what you are saying?
You may be in for some serious engine damage if you way overfilled it.

No problems with that pressure range. If the actual oil level on the dipstick was in fact low, (but nearly 3 quarts?? ) keep a close eye on the level. Check the oil level frequently like weekly and do it before starting the engine when it's cold. Also make sure the car is on level ground. You can also check the oil level after the engine has been off for a good 20 minutes. That will allow the oil in the upper part of the engine to drain back into the oil pan.

Have you looked under the car to see if there is any wet oil on the bottom of the engine or on frame components?

I can not see any visible oil anywhere, but on pavement where I park, underneath car, on sides. I got this car 6-7 weeks ago. The oil life said 61 percent so u was figuring to change it soon. Then oil light came on Thursday night.

2 ways. Go to the oil life and hold reset or the same was as almost every other GM with an oil life monitor - Turn the key to on and step the gas pedal right to the floor 3 times.

Are they history codes or current codes? H or C
The history codes although not meaningless, aren't priority. They may leave a trail to something that was or is going to be an issue.
Current codes that won't clear need addressed...

Clear your codes... go for a ride and then PULL your codes before you KILL the car... write them down and post them.
