What are the symptoms of a bad O2 sensor?

A failing or failed O2 sensor may not detect the engine’s air-fuel ratio running too rich or too lean. Common signs include an illuminated check engine light, poor fuel economy, rough idling or failed emissions testing.

Can a bad O2 sensor cause the check engine light to come on?

Yes. When incorrect oxygen levels are detected in the exhaust, the sensor will trigger the sensor to send a fault code and turn on the check engine light.

Will replacing an O2 sensor improve gas mileage?

A properly functioning O2 sensor can help the vehicle maintain the optimal air-fuel ratio for combustion, helping balance fuel economy, engine performance and emissions.

How long do O2 sensors last?

O2 sensors can last between 60,000 and 100,000 miles. However, O2 sensor longevity depends on numerous factors including heat, carbon buildup and normal wear.

Why choose GM Genuine Parts O2 sensors instead of aftermarket brands?

GM Genuine Parts O2 sensors are engineered to original equipment specifications for precise fit, form and function. They are designed to integrate seamlessly with your vehicle’s engine.
