WebFeb 9, 2008 · The 3 and 4 wire O2's simply add a heater circuit to the sensor. This allows them to warm up and go into closed loop faster. The ECM will not use the O2 sensor until it reaches 600mv output. If the O2 is mounted away from the engine like the header collector then it has a tendencie to cool off at idle and go to open loop. So a heated O2 is ... WebDec 23, 2009 · The Heated Oxygen Sensors (HO2S) are mounted in the exhaust system where they can monitor the oxygen content of the exhaust gas stream. The oxygen present in the exhaust gas reacts with the sensor to produce a voltage output. This voltage should constantly fluctuate from approximately 100 mV , high oxygen content = lean mixture, to … WebOxygen sensors, often also called O2 sensors, lambda sensors, or air-fuel ratio sensors, measure the oxygen concentration in your exhaust, communicating this information to the engine control module (ECM) to adjust the fuel mixture. This helps ensure that your vehicle is running as efficiently as possible, and minimizes emissions of unburned ... george fairweather boots
