That has now been replaced with another which works but is now causing a peculiar problem.
I've touched nothing else but this sensor so it has to be to do with this.
The engine STOP light comes on faintly when the fan comes on.
At precisely 90degrees the fan comes on, the light wont go out until the fans switch off when the engine cools down.
Ideas? (Switch is a Red Ringed Blue switch).
