What does O2 sensor mean on a car?
Apr 22, 2019. The oxygen sensor of your car measures the amount of oxygen in the exhaust gasses that exit the engine. It sends real-time data about the amount of unburnt oxygen in the exhaust system to the engine’s computer to determine the correct air-to-fuel ratio for the car’s engine.
What does the O2 sensor on a car do?
The sensor determines the amount of oxygen in the exhaust system. With a fully functioning O2 sensor, the engine can balance the amount of fuel used. In return, this allows for peak efficiency. How to determine if your O2 sensor is dirty? There are a few different ways that you can diagnose if your O2 sensor on your vehicle is going bad.

When did the planar O2 sensor come out?
In order to make the O2 sensor more capable of mass production, planar oxygen sensors were developed. This modernized O2 sensor was developed by NTK in 1990 for use in the Honda Civic and Accord.
Where is the 02 sensor located?
Oxygen sensors O2 sensors will always be located in the exhaust system. Their function is to sense how much oxygen remains in the exhaust that is flowing out of the engine, and report that information to the vehicle’s engine control computer.

How does Your Car Act if the O2 sensor is bad?
