What Does The O2 Sensor Do On A Car

If you’re like most drivers, you probably don’t spend a lot of time thinking about your car’s O2 sensor. That’s because its main job is to monitor the air quality in your vehicle and notify you if there’s a problem. But if you ever have to replace your O2 sensor, here’s what you need to know.

What is an O2 Sensor and what does it do

The O2 sensor is located on the exhaust of your car and it monitors the air/fuel mixture. It sends a signal to the engine control unit (ECU) when the air/fuel mixture is too lean or too rich. The ECU then adjusts the fuel injection accordingly to keep the engine running at its optimum performance.

What are the benefits of having an O2 sensor on a car

An O2 sensor is a device that is located in the exhaust pipe of a car. It monitors the amount of oxygen in the air, and it helps to control the engine’s fuel mixture.

The main benefits of having an O2 sensor on a car include:

1. Improved fuel efficiency.

2. Reduced emissions.

3. Improved performance.

4. Increased safety.

How to replace an O2 sensor on a car

If your car has an O2 sensor, it is likely that it has been replaced at some point in the past. O2 sensors are necessary for cars to function properly and they are typically replaced when the car starts to have problems with its emissions.

The most common symptom of a faulty O2 sensor is a decrease in fuel economy. Other symptoms can include:

-A rough or jerky ride
-A loss of power
-Engine noise that increases when the car is started cold
