My engine light keeps on coming on my '05 v6 and the codes P0108 and P0406 come upon my tuner. These are Manifold Absolute Pressure/Barometric Pressure Circut High (108) and Exhaust Gas Recirculation Sensor "A" Circut High (406). I had dual exhaust put on by a reputable dealer with stock GT mufflers, Dynoflow midpipes and custom H-Pipe. Are these trouble codes just telling me that there is more air/pressure running through my pipes, or is it a different problem?

 

I am having the same codes pop up on a 2007 v6 Automatic. I know this post is old...but did you find out what the fix was?

Ive tried cleaning MAF sensor, Cleaning Throttle body, and running seafoam through gas tank and upper hose from the egr valve. Anyways I cant get this light to go away. Please help if you can.

 

Your check engine light has just come on while you are driving down the road.

 

yes that is correct.
