One of my gauge needles is de-calibrated. Is there a way to re-calibrate it?

It depends on the year, make, and model. However, if the gauges don't have stoppers and do not move on their own, chances are they have gears that can be re-calibrated.
 
To start, first remove the plastic lens and carefully inspect where the other gauges rest (stopping point). If gauge for some reason has a stopper higher than it should then you can move it in the counter-clockwise direction until it stops at the same point as the other same-sized gauge needles.
 
If the gauge needle stopping point is lower than the other same-sized gauge needles, simply move it all the way over in the clockwise direction, then spin it back around in the counter-clockwise direction until it reaches the satisfied stopping point.
 
If you don't get it right the first time, you can repeat this as many times as needed until you get it just right. There is no need to remove the gauge needle from the cluster. Also, make sure the gauge needle can move freely and isn't pinched (too close) to the faceplate.
 
In the event that you find a gauge needle pinched. You can use a fork or plastic trim remover tool to increase that gap.
