Alright, so I just made a drive from Iowa down to Texas. Before the drive, and during it, she had no problem. Rode great. Then I get in it this morning and while driving it made this really high pitched whining sound and the service engine light came on. I'm at a total loss. While idling, it's very faint and not as often. It's not my A/C unit, or the alternator. I'm thinking its the Power Steering, but I don't have a leak, and it's not difficult to turn, but that's where the whining sounds like it's coming from. Just would like a more experienced point of view on it before I go buy parts that aren't needed.

What code(s) triggered the light?

The power steering pumps are notorious for whining on these cars. Does the pitch increase with rpm?
