Fault Code P02365 and P0236 S80 2002

I fired up my new Auterra Dyno-Scan PC based scan tool 'cause our early '02 S80 had the check engine on. The code was P0235 "Turbo/Supercharger Boost sensor “A” circuit". The pending code was P0236 Turbo/Supercharger Boost sensor “A” circuit range/performance. I used the clear trouble codes command and the P0235 code is gone but the P0236 code is still pending and the check engine light is still on. The Dyno-Scan manual says if there is a sensor short the clear command will reset the light.

Anyone got any experience/advice with this set of codes? I'm going to continue to drive it to see if it self-clears, unless someone screams DON'T.

Thanks for your help.
