Car Oxygen Sensor replacement & repair made easy

The sensor measures the amount of oxygen, or O2 present in the fuel / air mixture and engine emissions. Most cars have several oxygen sensors spread over the engine and its ancillaries; from the inlet manifold to the exhaust. Some cars even have a seperate sensor for each cylinder.

Usually the sensor puts out a voltage between 0.1 and 1 volt depending on the current passing through. This information from the sensors is processed by the engine's computer (ECU). The ECU in turn optimises the amount of fuel and air entering the engine to ensure optimal combustion and reduced emissions.

What does a oxygen sensor replacement involve?

The mechanic will read the ECU for possible fault codes related to the oxygen sensors.
The mechanic will inspect the sensor and ancillaries (like the electrical connectors).
If necessary, the mechanic will replace the sensor.
The mechanic will advise if other components need to be replaced as well.
The mechanic will check the sensors again.
The mechanic will test drive the car, if necessary the mechanic will make adjustments.

How often should you replace an oxygen sensor?

For an optimal combustion of the air / fuel mixture within the engine it is important to service the oxygen sensors as and when stipulated in the guidelines set out by your car's manufacturer. Professional and timely maintenance is essential to prevent further damage of other parts of the engine. Should you experience problems with an oxygen sensor, then it is advisable to have it inspected and, if necessary, have the sensor replaced.

What happens if I don't replace my oxygen sensor (or lambda sensor)?

Over time, an oxygen sensor can soil due to the dirty air passing along it. This decreases the sensor's ability to identify the amount of oxygen that is present in the area of the engine system it is situated. This can lead to the ECU not being able to regulate the fuel / air mixture correctly which can have as a consequence that the engine will run lean or rich. In turn the car can have poor fuel consumption, equally it might cause the car to fail an emissions test.

In many cases an oxygen sensor can be cleaned of dirt to restore its functionality. In other cases it can be that the oxygen sensor has really failed, in which case it needs to be replaced to prevent further issues and inconvenience.

Can I drive with a faulty oxygen sensor?

If you suspect there is any issue with your oxygen sensor (also known as an O2 sensor) or there are concerns about its age or condition, book an inspection with a professional mechanic immediate effect. Driving with a faulty oxygen sensor can lead to further complications on your vehicle.

Can you replace just one oxygen sensor?

A car usually has two oxygen sensors if it has a single exhaust pipe and catalytic converter, and sensors could be independently replaced. It is advisable to check with a professional mechanic whether it is possible to just replace one sensor as this can depend on a number of factors.

How much does it cost to replace oxygen sensors?
