Do you need O2 sensors without cats?
an O2 sensor does not need a cat to function properly. There are aftermarket fuel injection systems that use an O2sensors to keep fuel mixture anywhere you want, usually way richer then is safe with a cat.
Why is the O2 sensor in the catalytic converter?
The o2 sensor ensures low fuel consumption as well as reduced pollutants emitted from the engine. It is therefore an important component to help pass vehicle inspection. The latest standards of emissions require the presence of a second lambda probe, located after the catalytic converter in order to determine its effectiveness.
Where is the O2 sensor in a car?
The o2 sensor (oxygen sensor) is located within the exhaust system, upstream of the catalytic converter. Its role is to inform the ECU of the oxygen content of the burned gases that result from combustion. The o2 sensor helps to ensure that the amount of fuel injected into the cylinders for the air-fuel ratio is at an ideal level.
Why do I need to replace my Oxygen sensor?
2 – Why replace a Oxygen Sensor? A faulty oxygen sensor has the direct consequence of disrupting the engine air-fuel balance. This leads to an increase in pollutants emitted by the engine, as well as causing the engine to stutter and consequently fuel consumption to increase.
Can a spacer be fitted on a O2 sensor?
Although you can get around this issue on some vehicles by fitting a spacer on your downstream O2 sensor (the lambda sensor), there is a risk that normal functionality does not return. That would make it a challenge to track actual faults through this warning light.

What’s the average life of an oxygen sensor?
The lifespan of a Oxygen Sensor is 160,000 km on average, as long as it is not shortened by engine malfunction. Unburned oil due to engine misfire may contaminate the probe irreversibly.
