PO29900 - Turbo Underboost

I keep getting this error code but no MIL.

The car runs fine with no apparent hesitation or loss of power and as said, no MIL, but every time I clear the code, it returns.

I think it's possibly the sensor/s - any ideas? Where are these located as my Haines manual is OK for general stuff but doesn't cover the 205 twin turbo
