it could have been possible that condensation built up in your fule line and froze it slightly thus reducing the amnt of fuel going to your motor and when it unfroze watered down gasoline aint exactly going to burn as well causing the motor to sputter a bit and trippin the check engine light because the fuel mixture aint right. just a theory. if everything is fine on your car the check engine light should come off after a while.
