I worked it out in the end. The temp sensor works as some kind of resistor, and if the voltage drops below 1.5V it triggers the warning. What has happened is that my wiring has just come apart in quite a few places, meaning the voltage going back to the ECU is always going to be under 1.5V and setting off the warning.
