0630 and 0234 codes

[Coonrod]

I have these two codes



P 0630 VIN not programmed in PCM



P 0234 Turbo over boost



I will sart from the first. Put TST on about 2 months ago. with no codes. Something happened with box would not let power through to the in cab controller, but truck still ran fine stock power. So I sent it to TST for repair. I figured since it was off I would get the 037 fuel economy reflash done. When I took the TST off i did not take the boost elbow off. I would think that is where i am getting the 0234 code from too much boost without boost fooling????? And the 0630 from something done at the dealer. I did not check the codes today until today when I put the TST back on. So I dont know when exactly the codes were thrown, before or after TST went back on. HAs anyone had these codes if so what was the cause? And how long does it take for them to clear. Or I could get auto zone to clear them also right?



Thanks Brad

the codes will never clear by themselves. the check engine light will go off eventually of the problem does not occur for a set period of time. The only way to clear them is to have somebody manually do it.

No check engine light just the codes.



Any ida on what caused the p 0630?
