My 02... On some cars the CEL will cycle itself off. Meaning if something triggers it once and that situation does not reoccur, after say 10x of starting the car and shutting it off it'll automatically cycle itself off.
That reason is why a lot of people suggest disconnecting the battery to see if it comes back on or it was a fluke thing during an install. You read this a lot in forums about installing mods; not sure if it's relevant here but wanted to share.
