Hey Oli. Lets face it, there's never a good time for your car to start playing up, but just before a show is particularly bad timing!
How confident are you at tracking down the problem from the codes you got from PP2000? You could try to get the O2 sensor out of the donor car and see if that fixes it, otherwise you're looking at a wiring issue. You've got an ECU pin diagram so should be easy enough to test from the ECU to the harness connector behind the exhaust manifold. 2 of the wires are related to the heater circuit & the others are signal wires.
The second fault on PP2000 is essentially saying the ECU can't keep the air-fuel ratio stoichiometric. Most likely that's related to the O2 sensor, but in my case I got that code without any indication a sensor was involved. I changed quite a few sensors and actually made the problem worse with a cheap MAP sensor. (Never made that mistake again & now mostly go for Bosch, who were the OEM supplier for a lot of those parts). Finally it turned out to actually be a poorly installed cam belt which had put the valve timing out by a small amount, but enough to upset the ECU. (Installation by previous owner & I suspect they tensioned it without loosening off the cam sprockets).
Good luck on sorting it!
