been having a few minor issues with the corsa running cooler than I would like and slightly over fuelling. did find that the map sensor was playing up and not changing as fast as it should so replaced that but while carrying out diagnostic checks noticed the inlet air temp sensor was show a temperature of -40f changed for a different sensor and still -40f but the voltage changed slightly. so tried warming up the sensor and cooling it down, voltage rises and falls but temperature remains at -40f even with sensor unplugged still -40f I'm running vx220 software mapped at Courtenay sport. the -40f is what bothers me? surely this isn't right is it?
