WebOct 14, 2024 · The oxygen sensor can only keep the mix between about 13.8 to 15.6 when the theoretical best air fuel ratio (stoichiometric ) is 14.7:1. An A/F ratio sensor can help keep the mix to 14.5 to 14.9:1. This results in greater combustion efficiency and lowered emissions.] Note to Zeichen, of course you are technically correct.
