Definitely looks like two seperate problems....
Trying to remember if there was a TSB on this problem, but it should have been fixed by now........it was about the EGR freezing, and which EGR you had, top connection or side connection(Siemans)......in the tsb, you had to replace the EGR and harness, depending on which EGR you had.....
However, this code is usually about the pintle position sensor....
As for the other two codes, could be the speed sensor, the wiring to it, or the PCM....
In both cases, the only way to know for sure is with a scan tool....
