An automotive oxygen sensor, or O2 sensor, detects the presence of oxygen in your exhaust gases. They can be found in modern cars, trucks, and motorcycles. Its role is to maximize combustion engine efficiency and emission control. Once the sensor reads the amount of oxygen present, it can determine the appropriate amount of fuel to be delivered to the cylinders.
The O2 sensor prevents the so-called knocking from occurring, which can happen when an engine misfires or combusts too soon before it has finished burning both air and fuel.
You can find the oxygen sensors in the exhaust to monitor combustion efficiency in an engine. It can restore some of the air that burned during the combustion process with high-temperature oxygen gas. The sensor uses a heated filament wire or platinum wire as its heat source and emits a low-current electrical current in response to changes in temperature.
What Are the Signs of a Failing Oxygen Sensor?
Driving with a malfunctioning O2 sensor can significantly reduce your vehicle's overall performance. Some widespread warning signs can indicate oxygen sensor trouble:
- Irregular engine performance
- Sudden cranking or rough sounding engine
- Check engine light lit up on the dashboard
- Lower gas mileage
- Failed emissions test
If your vehicle exemplifies any of these symptoms, please take it to an auto repair shop soon.
When To Replace a Bad Oxygen Sensor?
You should get new oxygen sensors when they lose their performance or start displaying some of the signs above. When an oxygen sensor malfunctions or stops working, the engine will not receive specific information about how much oxygen is needed to get the perfect balance of air/fuel. As a result, it can cause the engine strain itself, leading to extensive damage and costly repairs. Furthermore, you'll be wasting an excessive amount of gasoline, which isn't cheap either.
