Oxygen (O2) Sensor Video

The oxygen, or O2 sensor, is part of your vehicle’s exhaust system and helps measure the air-to-fuel ratio in the engine. By monitoring oxygen levels in the exhaust, it allows the engine to adjust fuel delivery for proper performance and efficiency.

When the O2 sensor is not working correctly, it can affect how the engine runs. You may notice reduced fuel efficiency, a rough idle, or changes in overall performance. These symptoms can have more than one cause, so proper testing is important.

At Blackwell Automotive in Phoenix, AZ, we can help diagnose these concerns. We may begin with an inspection as part of our auto diagnostics service and evaluate related components within the engine repair and exhaust system.

Addressing sensor issues early can help maintain engine performance and support proper emissions control.

If your oxygen sensor or engine system needs to be inspected, call (602) 992-5478 today.
