MG TF 2004 Error Codes

Im getting two error codes using the Pscan:

P0553 - Power Steering Pressure Sensor Circuit High Input
P1539 Power To A/C Clutch Over current

There is no MIL light on.

Power steering is working fine, not hard to turn and not pulling
The car does not even have A/C, Has anyone else had these error codes? When i erase them they come straight back. Not an issue but is bugging me as to why its throwing up these codes,

Cheers, Neil

I get the same codes. Car drives lovely.

I suspect that P0553 only relates to Rover 75/ZT.
