Will bad O2 sensors throw codes?
Like other engine sensors, there’s no need to replace an O2 sensor as long as it is working properly and accurately reading the oxygen content of the exhaust. Such problems may not be bad enough to set a code, but they could have a detrimental effect on engine performance, fuel economy and emissions.
What are the signs of a failing O2 sensor?
Here are some of the most common signs that your oxygen sensor is bad.
- A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
- Bad Gas Mileage.
- An Engine That Sounds Rough.
- An Emissions Test Failure.
- An Older Vehicle.

Can a check engine light be an oxygen sensor?
It seems as though the check engine light and O2 Sensor codes have always gone hand in hand. I can’t even begin to tell you how many perfectly good sensors I’ve seen replaced for a rich/lean code, or as a cure to a service engine light that comes and goes. Fact is, when oxygen sensors were first being used, they did tend to fail.
