PROBLEM anyone chime in and help me out

[jeff71]

well i was driving and noticed my egrs were LOW, when i would let off the gas they would raise a little but driving they kept changing from 140 to 300s to 200s etc, checked the codes and got...

dtc code= po4od egr
temp sensor a circuit high

dtc code=p1000 obd system readness

what might these mean?......do i need a new sensor or do i need to reset my tune? and can i drive the truck without hurting it ....it just fell limp like slower then stock..and help would be appreciated..........

The manifold absolute pressure sensor. On your truck I am not sure were it is located.
