I have 10 error codes registering with my check engine light. The weird part is they all popped up at once!!
I have them with all the info I could gather. I am trying to figure out if I can replace or fix one or 2 things and knock out multiple codes as to not waste time/$$.
Please let me know if anyone has any thoughts.

2004 Chevy Silverado 1500 - 4WD buttons w/Auto btn.


ABS releated codes:
C-0222 - ABS wheel sensor gone
C-0227 - ABS related, unknown code
C-0265 - EBCM Relay - Possible relation to ABS Pump.

4WD related codes:
C-0306 - Power Train: Transfer Case
C-0359 - Low Range 4WD Discrete Output Circuit; Short to power for 4Low
C-0374 - Inspect wire harness to transfer case speed sensors
B-0790 - Wiring problem in transfer case control module (TCCM)
B-2725 - Transfer case shift control switch

Other codes:
P-0101 - Mass Air Flow sensor or circuit
P-0446 - Evaporative vent solenoid

Hopefully someone has some ideas. Also, with these codes, is my truck still ok to travel long distances?
Thanks!
