Code P0236?

I have a code P0236 Turbo Boost Sensor A Circuit Range/Performance. What is this telling me? I got it along with a P1728 Transmission Slip. The P1728 cleared when I pulled fuse 9 but the P0236 came right back. Also my coolant temp indicates 302* on my AE but my temp gauge indicates cold right after start up. Any ideas? Thanks, PK.

On the P0236 ... 0236 = Detected high boost signal at low idle. (Restricted MAP line.) (Inrange Fault)

From this on line manual ... 97-15A 7.3L DI Turbo Workshop Manual

On the coolant temp reading the PCM does not monitor coolant on the OBS rigs, instead it uses EOT, so it's just a phantom reading.
