Most modern vehicles are equipped with oxygen sensors, as they are essential for meeting emissions standards. However, some older vehicles may not have oxygen sensors, or they may have faulty oxygen sensors. If you suspect that your car may need an oxygen sensor, there are a few things you can check.
First, you can look for the following symptoms:
* The engine light is on.
* The engine is running rough.
* The fuel economy has decreased.
* The emissions are high.
If you are experiencing any of these symptoms, it is important to have your car diagnosed by a qualified mechanic. The mechanic will be able to determine if your car needs an oxygen sensor, and they will also be able to replace the oxygen sensor if necessary.
Replacing an oxygen sensor is a relatively simple and inexpensive repair, and it can help to improve your car's performance, fuel economy, and emissions.
