Want to avoid replacing your O2 Sensor?
Carbon Cleaning is your best option!

What is the purpose of the O2 / Lambda sensor?

The O2 (Oxygen) Sensor or Lambda Sensor as it is known in the the trade is located before the Catalytic Converter in the exhaust system.

The job of this probe is to measure the amount of oxygen left in the remaining burnt gases as they exit the engine and send this information to the ECU (Engine Management Unit). The ECU can then calculate the correct fuel / air mixture for the ideal combustion which lowers fuel consumption and in turn reduces emissions. This is important for passing MOT and roadside emissions tests.
More recent regulations require a second 02 sensor to be positioned after the Catalytic Converter so that the effectiveness of the converter can be measured.

Why you should the Lambda / 02 Sensor be replaced?

If there the sensor is faulty it will send incorrect readings to the ECU and therefore the calculated air to fuel ratios will be incorrect. This will cause the engine to stutter, run lumpy and increase fuel consumption.

    Just had the clean done on my 08 Lexus by Red. Fantastic service and really great guy (he saved me from reversing straight into his van!). The car is much smoother to drive, quieter, more responsive and there's an easily noticeable reduction in vibration through the clutch and gear stick. Will definitely use again.

    Had my 2007 ford focus St carbon cleaned today... Made a huge difference on the over run and really noticed that extra pull especially in first gear. Very surprised at the gains considering it is a petrol that already runs nicely I would highly recommend this treatment to anyone and if you have a diesel with a few miles on the clock do not hesitate to book it in now for a clean! 🙂 🙂 happy customer 🙂 🙂

When should the Lambda / 02 Sensor be replaced?

As long as it’s not shortened by other engine malfunctions the average lifespan of an 02 sensor is 80,000 to 90,0000 miles.

Exhaust leaks can damage the sensor probe which can lead to dangerously high temperatures. The probe canse also become contaminated by unburned fuel, if this occurs it is irreversible.
Following a strict servicing routine, including the usual oil changes, spark plugs, air filters etc, is required to ensure maximum life of the sensor.

Signs that your Lambda / O2 Sensor needs to be replaced:

  • The engine starts to stutter or suddenly suffers from reduced performance
  • The check engine management light illuminates

The easiest way to diagnosis a faulty Lambda / 02 sensor is with an OBD (On-Board Diagnostic computer). Unless you have access to an OBD reader and are competent in using one this should be completed by a professional.

Typically garages charge up to £70 for such a diagnostic, alternatively we include a FREE diagnostic with all of our Carbon Cleaning Services starting from just £89.99

Cleaning your Lambda Sensor / O2 Sensor?

There are numerous ways to clean or replace the Lambda Sensor / 02 Sensor with varying prices.

The costliest option is a complete replacement part. Most mechanics will recommend this – Why? It’s generally their only solution. The price of a Lambda / O2 sensor varies on average between £180 and £300. NOTE: Newer vehicles have two sensors and it’s not uncommon that if one has been damaged the other will have been as well
