P0603 internal control module keep alive memory Kam error

P006a map- mass air flow correlation bank 1

Tomorrow I will clean my maf sensor has anyone had p006a ?

 

I've had one since I bought the truck. It comes and goes. New CAC tubes/boots, turbo rebuild, turbo solenoid, exhaust manifold gaskets, y-pipes, ccv delete, map sensor, IAT sensor, egr delete....none of it made a difference. I don't worry about it anymore....much. But if you figure it out let me know. The only other things I can think of that would affect air flow or air flow metering would be the maf sensor, or a leaky charge air cooler.

The P0603 will go away by itself like the P1000. It always comes up when both batteries are disconnected. I used to worry about that too in the beginning.

Talk about hitting the nail on the head! Lots of info there, though it seems like a lot of trouble testing for a code that doesn't seem to affect performance, at least in my truck. And then throw in the egr and ccv deletes, and the test results will probably be skewed or indeterminate anyway.

 

I wasnt sure if the vibration was the engine or suspension but replaced the drive shaft and ujoint (both original with over 270k miles) and it runs straight now. When I get a round tuit I will clean the maf sensor and keep you posted

 

Did you replace the carrier bearing too?

I did not. I just read the link you posted though. It's drives straight for now . Thx for posting that tho
