I got the SES light today, and pulled the codes off the truck. A couple I have seen before, but a few are new.

P0603
P1247
P1211
P0542
P0640

I know the last two are the air heater, so thats probably not a biggie, but the low turbo boost, and the keep alive memory are new though. Anyone have an idea on what is going on?

I looked at all the boots, etc for the boost problem, thought I may have had a leak there, and I cant find anything.

Thanks again guys!

 

P0603 is from the Edge, so you can ignore it.

Also the P1211 code is extremely common when running a chip or tuner. If you suspect problems with the HPOP system (the IPR, ICP sensor, etc), switch to stock and see if you still get codes, or monitor with a scan tool.

As for the P1247, erase the code and see if it pops back up. That can be triggered under certain circumstances when you have a chip or tuner installed. If you don't notice any problems with boost or EGT's while driving, then it might be just a fluke code that popped up. If it continues to come up constantly, then you need to check for a problem.
