Disconnect the battery cable wait a bit, reconnect. If the CEL comes back, plan B go get a free code dump from a parts store. Dealers and mechanic shops will charge, parts stores do it for free.
I would do this in the reverse order so that you know what it was.
My last CEL was for MAF/MAP. The light only came on after 2 sequential failed “tests” which only run under higher rpm, full throttle.
