2006 Chevrolet tahoe 4wd -ABS, Traction light & Service Stability system message comes up, only code in system is P0455. problems comes & goes but worse on rough roads or in town. according to what i have read i believe Steering Position Sensor is faulty. lately though a new problem has occured, vehicle acts like brakes are on or trans slipping when pulling away from stops.... only when lights are on & code in system. If vehicle is shut off & restarted seems to work fine for a while. if it is sensor at fault, does anybody have a procedure for replacement. only 2007+ replcement is shown on YOUTUBE
