2014 Sierra 1500 4x4 -- 142,000

Ever find out what it is? Mines doing the same thing replaced the sensor twice works for awhile then starts doing it again, and it does seem to have something to do with be cold outside

mines got 137,500, I changed the filter and fluid at 120,000

137,500 --- runs like new Deactivated the active fuel management no problems other than the wheel speed sensor and the camera sensor 6 inch lift w/ 35's

My stabiltrak warning light kept coming on constantly and the ABS light also, turned out to be a broken wire on the wheel speed sensor. I have problems with the service trailer brake coming on, I havent figured it out yet, I did squeeze the things on the dash and it hasnt come back on and its been about 50 miles so far.
