I cleared the code, and drove 6 hours home without the light coming back on again.

The only other time I've seen this code was on my Hyundai Genesis Coupe I used to own, and I only got it when using an aftermarket box designed to remap the car with a custom tune (and it wasn't working properly).

The dealer (of course) told me they "never saw a CEL come on the whole time they had the car, and suspected it was just a fluke, because they just washed it before I drove away with it".

Is this a known sign of any parts starting to go bad that I need to replace?
