In my car it shows the temperature as above 250 degrees before the cars even started and it doesn't change when warmed up. Could this be a sensor problem or gauge? Or even earth? Is there an easy way to check which? If sensor can I use any replacement sensor? Its some aftermarket gauge, I can't see a name on it but I have seen them at supercheap before.
I'm stumped.
Cheers in advanced
