Toyota FJ Cruiser Oxygen Sensor

The oxygen sensor is situated at the exhaust pipes and is used to detect the oxygen levels in the exhaust as it gets released from the engine. This check is important to understand whether the engine is running too rich or lean. In rich conditions, the oxygen level is low and the quantity of fuel is high and vice versa in lean running conditions. This information helps the ECU to adjust the fuel entering from the fuel delivery system to the engine for proper combustion and correct fuel-to-air ratios. If not corrected, it may lead to increased fuel consumption and increased emissions from the exhaust. It may also damage the catalytic converter and other engine components.

Like any combustion process, when the air and fuel mixture gets burnt in the combustion chamber, exhaust gases are released. These gases contain elements like oxygen, carbon, and many more. The gases find their way out of the exhaust pipes. As these gases pass through the exhaust system, the oxygen sensor present in the exhaust manifold, calculates the amount of unused oxygen in the exhaust gases. This information is then sent to the Engine Control Unit for further analysis. The ECU is responsible for the proper functioning of the engine and the associated components, which may also include other sensors. The ECU is the brain of the engine as it collects the data and makes the right decisions. It analyzes the oxygen levels and reads if the combustion process is taking place properly or not. Thus, it will know if the engine is running lean (more air, less fuel) or rich (more fuel, less air). It will then instruct the fuel delivery system to act, which will adjust the quantity of fuel for proper combustion. This will also reduce harmful gas emissions and provide better performance.

The sensor is usually positioned on the passenger side of the vehicle, mounted directly on the exhaust pipes near the catalytic converter.
