Has anyone seen a P2563 code thrown on a 08 Dodge Cummins? My truck just threw it last night and from what I can find out it looks like a GM code relating to the Turbo. I have had the P2579 code about a month ago as well. Any thing I need to do here to protect the Turbo?

P2563 - Turbocharger boost control position sensor - range/performance.You need to check the sensor if possible and also do you have the waste gate altered? Check to make sure that the turbo is good working order. Check the wiring at all connections that you can see, one could be loose or corroded.

I'm not aware of any alterations since I just got this truck a month ago. I plan to check the wiring to the sensor based on the P2579 code. It has happened only when doing very short trips around town which made me think it might be getting gummed up in the turbo. Thank you for the response.

Is it possible that the waste gate is stuck closed and you have an overboost code?

There is no wastegate on a 6.7, and that code is not the one that pops up with an actuator issue. Is there any warranty on the truck still?Do you know it's history? Any recent software updates? Any warranty repairs?

Unfortunately I just bought it with 200K miles. I added a 3 month warranty on powertrain as that is all I could get with a truck with this many miles. If it pops the code again I'll try to take it in. I drove it pretty hard and used the engine brake a lot and the code has not come back yet. I wish I knew the history. I think I will call my dealership tomorrow and see if they can give me the history based on the VIN. I would also like to know what software version I'm running on the ECM.
