Placed in the vehicle&#8217;s exhaust stream, the Oxygen sensor monitors the amount of unburned oxygen after combustion, producing a voltage signal. It works by comparing the oxygen in the hot exhaust to the ambient air outside. This signal informs the vehicle&#8217;s Engine Control Unit (ECU) if the air-to-fuel ratio (AFR) is &#8220;rich&#8221; (too much fuel) or &#8220;lean&#8221; (too much oxygen). \u00a0 The ECU uses this real-time feedback to constantly adjust the fuel being injected, aiming for the ideal 14.7:1 ratio. This precision is essential for the catalytic converter to efficiently reduce harmful emissions.
