HELP!!! Funky acting oil pressure guage and more....
Hey everyone. I was driving down the road the other day and experienced a huge loss in power. The check engine light came on, and soon after, I saw the Oil pressure drop to nothing. It then came back up and was doing that till I limped it home. I noticed that I had 1100* EGTS, and 7 PSI boost levels. That scared me alot. I got it to a shop, since I couldnt get it to Winston Salem to Scott, and he is doing a diag on it. He pulled 9 codes! Here they are:
ok, the codes 0472,0475,0541,0640 dont mean a thing to me. Cause I have no EPBV or Intake air heater on my truck. So I understand those codes.
0257 is a low boost circuit A code. Whats this mean?
1207 is a ICP system fault. IPR is stuck. means my IPR is bad then right?
1211 is a ICP pressure above/below desired. IPR valve failed or stuck. again, IPR valve is bad right? could it also mean my ICP is bad too?
1249 is a wastegate steady state code. Whats this mean?
1668 is a PCM/IDM communication error. whats this?
I left Scott a msg on his phone, and I am awaiting a call back from the shop with a further diag today. I just wanted to see what you guys thought of my problems.....thanks!!!
