The Toyota Oxygen Sensor, a part of the emission control system, is used to estimate the ratio of air and fuel in the engine's combustion chamber. The amount of oxygen in the exhaust is measured by the sensor and sent to the engine control unit (ECU). The ECU makes adjustments in the fuel injection to attain optimal efficiency. If your car experiences rough idling, increased emission of pollutants and reduced fuel economy, you may consider replacing the oxygen sensor with a new one.
If your Toyota Oxygen Sensor is not functioning properly, you must replace it as soon as possible. Buy Auto Parts has a wide range of car parts for every car make and model.

Use rubber gloves to extract the Toyota oxygen sensor from the gasoline bath. Dry the sensor with an old cloth or paper towels. Return the cleaned sensor to its proper place in your engine, and take your Toyota to be re-inspected.
