Turbo On It's Way Out?

[onyx]

I will try and make this brief. Last week my factory boost gauge started to act funny. At idle it would lay right over to 40 down to 20 back to 40 and so on. Threw the codes P06A7, P0472 & P000. At hiway speed all will seem fine then out of the blue the gauge will sweep to 40 and have a noticeable decrease in power / runs crappy for about 3-4 seconds then just stick at 40 and run fine. It will stay there a while then return to normal readings, my edge insight will show the same thing.

It went to the dealer today and they replaced a ebp sensor which cleared the CEL but it still does the wierd boost / loss of power. Any thoughts? Thanks!

Did they change your map sensor??

No they did not.

It looks like you have a vref problem, could be a bad 3wire connector shorted wire or possibly another sensor that uses vref failing. Are all of your egr connectors unplugged like there suppose to be as well as all the sensors in the exhaust, I know there not all vref circuits, just wanting to make sure that stuff is the way it's suppose to be
