Low mileage DTS with very little history of faults, suddenly was showing the same 5 fault codes. It would go to a neutral idle [high idle] eventually shutting down completely. Trac control, Skid control, ABS, TPS correlation! Final fix was that the Throttle motor was Failing, 2 TPS’s did not match positions because the motor was going inactive. After 06 all are electric throttle, no throttle cable, simply a sensor at your foot and an electric drive motor at the throttle plate.
