I am getting codes P2141, P0102, P0487, P2A00, P2A01, and U010C. I am all stock, no mods. Does anyone know what would be causing all of these?

P0487 = egr Airflow Throttle Control Circuit A Open
P2a00 = o2 Sensor 1/1 Circuit Performance

If you are all stock, I would take the truck back to the dealer with your codes that you have listed. I would have them fix the truck and ask the tec what was wrong with the truck.
I use to do this when my truck was stock and under warranty. The tec would always answer my questions and there usually was a print out listing the code and the description of the code.

If you are stock, use that warranty for everything. You paid for it. All built into the selling price. :thumbsup:

The truck is repaired. They found #37 fuse blown. Everytime they replaced the fuse and then hit the EB button it blew the fuse. The reason it was blown was a short in the VGT Actuator. This also caused the fault codes for the other sensors. After replacing the VGT Actuator and the blown fuse all was good.
