What is the main functionality of a lambda probe?

The lambda probe is a sensor that measures the amount of oxygen in the exhaust gases, allowing the engine control unit to regulate the fuel and air ratio.

What is the difference between a lambda probe and an O2 sensor?

Both terms are used interchangeably – the O2 sensor is the English name for the lambda sensor. In practice, they refer to the same exhaust system component.

What are the symptoms of a damaged lambda probe?

The most common symptoms include a loss of power, increased fuel consumption, unstable RPMs and the "check engine" light coming on.

Is the lambda probe compatible between different car models?

Not always – compatibility depends on the manufacturer, year, and engine type. It's best to select a part by its VIN.

How often should a lambda probe be replaced?

On average, every 100,000–150,000 km, although this depends on driving style and fuel quality.

Do O2 sensors affect fuel consumption?

Yes, a damaged sensor can increase fuel consumption by up to 15–20% because the engine control unit does not receive correct data.
