Today i was comming into work and came around a turn and spund my tire and that something popped up on my screen that has mpg and all that suff but when off before i could read it, I check my aerofore gague for any check engine light and this is what i got P0503 Vehicle Speed Sensor Intermittent/Erratic/High, is that bad if so how do i fix ect ??

 

More than likely it's from your tires spinning. Clear it and see if comes back. If so you'll need a wheel speed sensor.
