I'm getting a load of HO2 sensor errors which I think are down to loom problems. Also, the fuse for the sensors keeps blowing too (can't remember the fuse number, it's in the auxiliary box. HEBO sensor I think it's listed as).
Good luck...

hi there
check the wiring to the lambda sensors and the fuse (#40). the rear (downstream), isn't that important, it's the pre cat one you need working. they start to need replacing at the 80,000 miles mark.
u1451. not seen that one before.  is the car running, as that's for the PATS system.

hi there
as i said, check the lambda sensor(s). http://www.fordscorpio.co.uk/obd2scan7.htm
also check if the exhaust manifold is cracked.
then give the MAF a clean up. http://www.fordscorpio.co.uk/cleanmaf
then the IAC Valve ( A in diagram). clean with carb cleaner, then a small drop of a light oil (3in1 or something) on to the sliding valve bit. http://www.fordscorpio.co.uk/obd2scan7.htm
If the code had the 'P' in front of it, it would be this.
P1451 Lack of Response From Passive Anti-Theft System Module - Engine Disabled.
try all these things first and let us know how you get on.
