The normal air-fuel ratio (AFR) sensor reading for most gasoline engines is typically around 14.7:1, which represents the stoichiometric ratio where the engine burns fuel most efficiently. This means there are 14.7 parts of air for every part of fuel by weight. However, this ratio can vary depending on engine design, operating conditions, and fuel type.
