This information is then relayed to the ECM. The ECM uses this information to adjust the fuel delivered to the engine. A Heated Oxygen sensor contains a circuit dedicated to operating a heater that warms up the Oxygen sensor faster than the exhaust gasses could. This shortens the time the engine needs to achieve closed loop, which decreases emissions. Circuit Schematic Diagram: Component Location & Image:
