Many Codes Need Some Help Here????

OK well had the PCM read about a week ago and the following codes came up
P0122 TP Sensor Cir Low (Fixed)
1406 EGR Pintle Position Cir
1558 Cruise Vacuum Depletion
1562 Cruise Control Vac Sol
1561 Cruise Control Vent Sol
0300 Misfire Det

Can someone please explain if these are related or not as far as the TPS
being bad and messing the other stuff up?
I can hear a knocking noise when I start the engine(just had the oil changed)
The Cruise Control Will activate for a sec and then just shut itself off. Obviously something is wrong but the manual doesn't show the codes after the TP Sensor Which is fixed
Thanks for the Help and Godbless,

Since the TPS problem was resolved, you should scan again for current trouble codes. If the Cruise problems still exist, check the wiring at the cruise servo module. Check the wiring at the EGR valve. The RG is in a position close to the TPS, so that wiring may have been disturbed in the process of repairing the TPS.
