Those are all low voltage codes stored in your vehicle. Has the battery gone dead recently? Have you replaced the battery or alternator recently?
Usually these codes set as a result of an electrical issue, usually a battery problem. If you haven't done any repairs, I would suggest to start by checking the starting and charging system on the Yukon. You may need a new battery and that can fix all those codes.

Hmmmmn!!! That makes sense.
In the process of the electrical diagnosis, the battery died cause the engine was off but my headlights were on.
The car had to be jump started for the diagnosis to continue. That's when this codes came up.
I don't think it's a battery or alternator problem though. My battery was very strong b4 then.
The reason for my diagnosis was cause the traction warning light came on while driving & I could feel a slight loss of power. This happened on 3 different occasions within a week. What could be the cause of that?
I haven't driven the car since the diagnosis cause I'm out of town till Monday. Do u suggest I do another diagnosis when I get back. HELP!!!

I would recommend clearing the codes, making sure the battery is fully charged, and then just driving the vehicle and see what happens. Some codes may return if you have a problem, and some may not set again. Since the battery was drained prior, you really need to start fresh and clear everything out.
If you do have a strong battery, and no other charging issues, I would think the codes should not reset.

P0121 - Throttle Position Sensor 1 Performance - Probably a bad throttle body, and needs replacement.
B0081 - Passenger Presence System Error - This has to do with the airbag system for the front passenger seat, it can tell when someone is sitting in the seat or not and turns on/off the airbag accordingly. Normally there is a problem with the module, or wiring connectors under the seat. This can take a bit of diagnosis to determine the cause.
B2645 - Ambient Light Sensor Circuit - This is for the sensor on the dash that detects whether it is day or night. Usually the sensor need replaced.
C0267 - Low Brake Fluid Detected - This is for the sensor in the master cylinder to detect if the brake fluid is low or not. Sometimes you can replace the sensor, or other times you need a new master cylinder assembly.
C0899, C0900 - These are the low voltage codes I explained previously. Either due to a faulty battery or something wrong with the charging system.

I would ONLY recommend the dealer, no matter the price. You really need to install GM parts on a GM vehicle. Otherwise you'll end up replacing them over and over.
Remember this....you get what you pay for.
