Ok,These codes are set because the PCM detects that the check sum value is incorrect for 0.05 second &The PCM detects that the TAC system has a process sequence error, clock error, or processor is not operating correctly.This problem is usually the throttle actuator control.Before replacing the TAC check the wiring from the PCM to the TAC,I have seen some of the wires broken inside the insulation within a foot of the TAC.
