Camshaft sensor check engine light

[Shehadehd]

So this weekend I took the car on an extended drive; I put about 600 miles on it. Today, I was leaving the parking lot after grabbing some coffee when the cel came on. I pulled over and read the code and it give 0348 Camshaft Position sensor A Circuit High Right Bank. However, The car ran just fine and I didn't feel any difference in power.

I cleared the code so that I could drive the car back to the hotel. During the drive the car had just as much power as it always has and nothing seemed wrong. The check engine light remained off for the full 15mi back to the hotel.

When I got back I felt like I now hear a new sound coming from the engine, right behind the front engine cover. It sounds like a static noise, almost like grinding but not quite. When I'm driving, I can't distinguish it over the car and when I stick my head under the car, I can't hear it. I'm not sure what it could be. Maybe I'm imagining it, or maybe it's unrelated.

I guess my main question for the post is, besides a faulty sensor or circuitry, what can that error code come up from? And with the car running perfectly fine and the cel light not coming back on for the ~15mi, is everything ok? Lastly, could this 'new' noise be related and do you have any idea what it could be?

I'm currently 70mi from my house and 30mi from a friend who can help me diagnose it. Should I attempt the drive?
