Toyota Oxygen Sensor 

We cannot deny the fact that automotive exhaust emissions and the gas prices that never seem to stop increasing have been bothering us these days. These factors really encompass a great effect to each and every one of us. But don’t you know that we can get rid of these problems if we only recognize some devices that have been designed to help us in working out this problem?

Yes, there are equipments and devices that would respond with this kind of problem. One of the most important technologies that would reduce exhaust emissions and that would improve fuel economy is the oxygen sensor - a part of the emissions control system that is mounted in the exhaust manifold downpipe facing the catalytic converter or between the exhaust manifolds and the catalytic converters which feeds data to the engine management computer.

 

Originally called a “Lambda Sensor”, when it was first used in fuel injected European cars, the oxygen sensor monitors the level of oxygen in the exhaust so an onboard computer can regulate the air/fuel mixture to decrease or to reduce emissions. The speed with which the oxygen sensor reacts to oxygen changes in the exhaust is very crucial also for accurate fuel control, top fuel economy and low emissions. For that reason, cars that have been produced since 1980 have oxygen sensors.

But like any other car parts, your Toyota oxygen sensors won’t last forever. The normal aging process will eventually cause your Toyota oxygen sensor to stop working. As it ages, contaminants from normal combustion and oil ash accumulate on the sensing element reducing the sensor’s ability to respond quickly to changes in the air/fuel mixture. Not only that, the sensor’s output voltage might not be as high as it before, giving the false impression that the air/fuel mixture is leaner than it actually is. The result can be a richer-than-normal air-fuel mixture in different operating conditions, resulting in much higher fuel consumption and emissions. So, if you have damaged Toyota oxygen sensors, replacing it right away is necessary.
