Ideas?

Been fine for 70k miles or so, now throwing these codes and boost goes randomly crazy between 10inhg and 10psi or so, pretty much randomly.. works fine at idle and full boost.. I doubt all these things failed at once, but dunno Could the first one cause the 2nd two?

16395 - Bank 1: Camshaft A (Intake)
P0011 - 002 - Retard Setpoint not Reached (Over-Advanced) - Intermittent
16622 - Manifold Pressure / Boost Sensor (G31)
P0238 - 001 - Signal too High - MIL ON
16490 - Manifold / Barometric Pressure Sensor (G71) / (F96)
P0106 - 008 - Implausible Signal - MIL ON

Clear codes and start the car letting it run for maybe 30 seconds and see if they all come back. I suspect the timing one is sympathetic to the real problem, which means it's the signal from one of the sensors or the sensor(s) themselves. I have no idea where those are, but if someone knows and can post, I would start by tracing hte wiring, checking for corrosion, lose connection etc.

Thanks... Ugg. Maybe I'll punt and take it to the shop for them to fix the wrong thing as normally happens.... I did clear codes, and still there, so something is amiss, and judging by the wild boost variations, something is wrong in the boost control.
