A car needs a good balance of oxygen to create the spark and burn the gasoline it uses for energy. When an engine runs lean, it can stall or show other performance issues. The oxygen sensor helps keep that in check by monitoring the amount of oxygen in your exhaust. It communicates that information to your vehicle’s computer to help optimize combustion.
They Monitor The Amount Of Oxygen In Your Exhaust
The oxygen sensor (also known as a lambda sensor) monitors the amount of oxygen in your exhaust to help control emissions. It sends this information to your car’s engine computer (ECM) so that it can adjust the air-fuel mixture and improve fuel efficiency. A bad oxygen sensor can cause your check engine light to come on and other problems with your car’s performance. These include a rough idle, misfiring spark plugs, lack of power, stalling or even an increase in your vehicle’s fuel consumption. Most oxygen sensors use a core material called zirconia to generate voltage in relation to the amount of oxygen in your exhaust. This voltage tells the engine computer whether the mixture is rich or lean.
Most vehicles are now equipped with a more sophisticated type of oxygen sensor that uses a wider radio frequency to deliver the correct voltage signal. These newer devices are more efficient and improve the fuel economy of your car while also reducing emissions.
They Help Control Emissions
Oxygen sensors for car help control emissions by monitoring the air-fuel ratio in the engine. They then send a signal to the engine computer to change the ratio of fuel to air so the vehicle runs efficiently and produces low emissions. The sensor works by using a platinum electrode to produce a voltage depending on the amount of oxygen in the exhaust. When the oxygen level is rich, the sensor outputs a higher voltage. When the air-fuel mixture is lean, the sensor outputs a lower voltage.
Nowadays, many oxygen sensors use heated HEGO (High-Efficiency Gas Oil) technology to warm them up more quickly so they can intervene in the feedback control system sooner and keep emissions within acceptable levels. This allows vehicles to produce more power, fuel economy and reduce the risk of damage to the catalytic converter. Today, most new and some older vehicles have at least two oxygen sensors that monitor the air-fuel mixture in the exhaust flow before the catalytic converter. This second sensor also measures the efficiency of the catalytic converter to keep emissions low.
They Are Easy To Replace
If you need to replace an oxygen sensor for your car, it’s not a difficult job. You can easily twist off the old one and install a new one. Oxygen sensors are located in the exhaust manifold and measure the amount of oxygen in your exhaust. They then send this data to the engine computer. Visit here Suncent auto parts online.
The engine computer adjusts all of your vehicle’s systems accordingly, which makes the oxygen sensors a crucial part of how your car runs. When they fail, your vehicle will not be able to set the air-fuel ratio correctly. This can result in a number of problems, including poor fuel economy and emissions issues. If you notice that your vehicle is filling up the gas tank more often than usual, you may have an oxygen sensor issue. This is an easy fix that will improve your fuel efficiency and save you money.
They Are Expensive
When it comes to replacing a faulty oxygen sensor, a vehicle owner can expect to pay between $50 and $250 depending on the brand. This includes labour costs, so it’s a good idea to find a mechanic who can help you out. A faulty oxygen sensor can cause many issues with your vehicle including poor fuel efficiency and rough engine performance. This is because the sensor helps control engine timing, combustion intervals and air to fuel ration. The number of oxygen sensors in a vehicle depends on the type of engine. For example, traditional V6 and V8 engines typically have three O2 sensors.
Final Word
Before bringing your vehicle to the mechanic, it’s important to understand how many O2 sensors your vehicle requires based on its engine size. Understanding this information can save you money on the labor charge and prevent you from voiding your warranty.
