Technical P0238 Fault Code: Suggestions for Remedy?

[regandavies]

My Fiat Panda 16v Multijet (2006) had the engine light come on for after five -10 miles, and the turbo cut out. Engine light simultaneously came on (continuously, not flashing) till end of ride. Engine light out the next time I drove it, but after 5 -- 10 miles the engine light came on again when I accelerated hard and the turbo cut in -- only to cut out. This is now occurring as a regular feature. By keeping the revs down,with no sudden acceleration to make the turbo really boost, I can ensure the engine light stays off, but when I accelerate strongly with a warm engine, the engine light comes on again.
Fault code reader says: P0238 Turbocharger boost sensor A circuit high input. (No other codes actual or pending).
I followed correspondence on a similar fault on this site and replaced the MAP filter with a new one. However, symptoms remain unchanged.
Has anyone got any suggestions, or has anyone had anything similar? The car has done 15,500 miles.

Many thanks.

Thanks for replies: To 306 Maxi: Car just out of warranty.
To T14086: Rear of engine, driver's side of centre. Remove air cleaner etc to get to it. No doubt about it ... I did replace the MAP sensor.
