Advice please. Been getting the check engine light along with traction control and scanned it. It gave me 3 codes C121C, P2638 & P0369. Replaced the camshaft sensor bank 1 “passenger side”. Cleared the codes and drove for a day and a half and the check engine light with traction control came back and the car is kind of in limp mode. I checked the wiring at the camshaft sensor and it looked. Is there anything I could do before I take it to the dealer?

If you are still getting p0369 it might also be the crank sensor or it's wiring, see attached pdf. The relationship between the 4 cam sensors and the crank sensor is important. Also anytime you have problems with camshaft sensors you can always swap sides and see if the code follows the sensors to the other side, if it doesn't follow it then no need in getting a new one to replace good parts with good parts. Also just a note each cam sensor unit actually contains two sensors one for the exhaust cam and one for the intake cam on each bank. The tone wheels on all 4 cams are magnetic and sometimes they get metal fuzz on them. Whatever you do don't stick a magnet in the hole to clean them as the cleaning magnets field will damage the tone rings magnetism. Proper way to clean is with the valve cover off and a rag if the "fuzz" appears to be excessive.
The other two codes are torque reduction codes related to shifting. I would resolve the p0369 before going after the other two in case they resolve with the p0369.
