If you find that your Toyota T100 is not running as well as it ran when it was new, a proper tune up may be in order. While most people know to change the oil, the air filter, and spark plugs, many are unaware of a vital component located in the exhaust known as the oxygen sensor. A Toyota T100 oxygen sensor is located on an exhaust pipe upstream of the catalytic converter.

It measures the ratio of oxygen to exhaust gases within the exhaust mixture. The sensor communicates with the engine’s electronic engine management computer, which makes the necessary changes to the mixture.

If the Toyota T100 oxygen sensor detects too much oxygen in the exhaust, the computer will add more gas to the combustion chamber. A faulty oxygen sensor will make itself known by a poorly running engine. Poor fuel economy is a major indicator of a failing sensor. A sensor that is not working properly fails to detect oxygen, and the engine management system will, by default, increase the amount of fuel it injects. While this condition will cause the engine to run rich, it will keep running, although poorly. It may cough and stumble, and, ironically, the addition of too much fuel will actually rob you of power, since you will not be getting a good burn of the gasoline. The unburned fuel deposits can end up sticking onto your cylinder walls and onto the piston head, further reducing the efficiency of the reaction. Changing the oxygen sensor is not a difficult job, although it can be somewhat time consuming.Replacement of You can order a new Toyota T100 oxygen sensor from our easy to use online ordering system.
