I tried the diagnostic program and the gauge moves all the way from min, mid and max. I looked at the computer with a scanner and it was showing temperature changes. I'm not sure its consistent though? But it's not showing up on the gauge.
Is the sensor bad?
Where is the sensor?
Any thoughts would be helpful.
