WHY DO I NEED AN OXYGEN SENSOR?
Oxygen sensors are designed to monitor the amount of oxygen that’s in your car’s exhaust stream, as a marker of efficiency and to confirm the catalytic converters function properly. They sense whether your engine is running an air/fuel mixture that is too rich or too lean by oxidizing a portion of the oxygen as it comes through the exhaust system. That reading is then turned into a voltage signal that is sent back to the engine control computer, which then adjusts fuel metering and timing to maintain an optimum mixture. This is something that’s constantly changing in real-time, according to engine load (i.e. hills), acceleration, engine temperature and warmup period, and other factors.
