Check engine light after intake valve cleaning

Looking for some guidance. Used CRC intake cleaner and followed instructions. While adding the cleaner, it tripped check engine light and after I let it sit and drove on highway it remained on. Assuming issue was bad air fuel level while adding cleaner. Will it clear on it’s own or need to be reset manually? Have a 2018 sv with 20k. Thanks

Has anyone else had a CEL after doing a CRC chemical clean? I'm thinking of doing mine after talking to the dealer and they said it would be over 400 bucks to clean intake and throttle body...plus extra to reset the IAC (I think it was the IAC....re-set something after cleaning). No this isn't a walnut blast job, just some "special" dealer chemical. Obviously I don't buy the BS....I suspect they just use a CRC-type product.
