Universal Oxygen Sensors

Automotive Universal Oxygen Sensors


The oxygen sensor is required by the combustion engine as this helps in adjusting the air fuel ratio in it. This task is accomplished by sending a specific voltage to the electronic control module. Many other sensors are at work in order to send signals to the ECM. The different sensors work together so that emission control system can be managed in an efficient manner. The sensor is vital for reducing the ratio of air fuel of a car.

The oxygen sensor is also known as a lambda sensor. This is one device used for evaluating the oxygen level in a liquid. Also, this is utilized for measuring oxygen level in gas. The original sensing part is made with Zirconia which is a white crystalline oxide. This is formed in thimble shape on both sides. The available types are heated and unheated and a little coating of platinum.

Don't worry when there is malfunctioning of your oxygen sensor because your car will still run. However, you should expect that it will not run as efficient as it is with good working sensor. Moreover, you will notice more exhaust emissions and increased usage in fuel. With the two sensors, the heated type of oxygen sensors can last to about a hundred thousand miles while the unheated ones can only run up to 50,000 miles.

Failure in the sensor can happen because of the accumulation of soot. Because of this, the second sensor won't be able to last for a very long time like the first. Furthermore, this is also caused by the damages in the engine parts too and the dirt that has been collected. When you have a bad sensor in your car then the mileage will be affected and reduced to 20% less. However, this usually depends on the driving and vehicle condition.

In many cars, the engine light can tell you that there is failure in the sensor for oxygen level as this will show light. However, you may not observe this in the old car models since the light could get burned. And when you have just newly purchased a used car, then the light may have been disconnected by the past owner. Hence it is important that when you take your car for a tune up then you should request the mechanic to check it.

With a car that has a newer model, then you won't have a problem with this. You will just need to connect it to the electronic control module and you will then be getting a report regarding the condition of the oxygen sensor. The engine light also works with modern cars and the ECM will give you the information about how the sensor is working. With older cars though, you cannot depend on the engine light. And when you choose to check the car manual yourself, then you should read the car manual.

In replacing your oxygen sensor, you won't have lots of difficulty. In fact you can do the process of replacing a faulty sensor without the help of a trained mechanic. There are lots of mechanics that call this method as the DIY method. Only simple tools are needed to do the procedure. The tools that you need include a new sensor, a flat tip screwdriver and an adjustable crescent wrench.

When it comes to the removal of the sensor, you should know that the process is different in each vehicle. And there are some things that should be removed or replaced as you do the procedure. However, the general method for replacing the sensor is detailed here. First, you have to locate the sensor. The sensor in most vehicles is found in the exhaust. For the front wheel drive engine, the sensor is located at the engine's front side as you open the hood. In rear wheel drive engines, the sensor is located just below the donut gasket.

You can remove the sensor when you have already located it. Look at the sensor first and study the wiring harness that could be removed through the tip of the sensor. Pull the device somewhere and just examine the engine so that you will be successful in doing this. When you remove the sensor, you won't have a difficult process if you remove the harness too. Use the adjustable crescent wrench tool and adjust it to the right size to unscrew the sensor in the exhaust. Also, you can employ a lubricant when you loosen up the seal of the sensor.

Take the new sensor out after you have done this step. Replacing the old sensor with a new one can be odd since you should be connecting the wiring already. Adjust the sensor until it gets bound to the wiring. Make sure that you tighten the device in place. At first you may fail but you can take several tries too. Also, when it comes to replacing your oxygen sensor, you should be working with a cool engine. Moreover, use gloves and goggles in the process as well. These will ensure that your eyes and fingers are protected as you carry out the procedure. Don't force things too. Prevent trouble by ensuring that the part fits perfectly without so much difficulty.
