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.

    Today I had a shot of James's new seat Leon Cupra and it drove very well, he then remapped it taking it from 240 bhp - 300bhp. I then had another shot after he remapped it and the diference was massive, the car pulled a lot harder and smoother through every gear

    positive review  Went to see matt today at horley site, bought an 07 plate honda crv cdti yesterday so thought i would see how good a 3 stage carbon clean was! I can honestly say it has made a massive difference, the engine ticks over a lot smoother, and the acceleration difference is just incredible! Would highly recommend matt and his team, very polite, informative and professional service. Well worth the money in my opinion!!

  • Andrew Edwards AvatarAndrew Edwards

    I had my Jaguar XKR carbon cleaned and although sceptical I must admit at idle the engine is a lot smoother and under hard acceleration it seems much more responsive so all in all I'm very happy with the results. I would also say that Matt is very knowledgeable about his product and professional.

    Linda Deeks AvatarLinda Deeks

    Had heard a lot of good things about this young mans work. Seemed too good to be true but decided to give it a try I am so glad I did. James arrived right on time he said. Explained everything he was going to do to car and told me he expected I would get at least 46 mpg .At the time my Ford galaxy was getting 43.5mpg. Also car would have more power to it. Well when he had finished I took car out for a run .It seemed as though I was driving a new car. Very smooth and lots more power as I realised when I overtook traffic. His next promise was mpg .He came up trumps on that too. From 43.5mpg.I am now getting 47.3 mpg. I would highly recommend this young man and his services. Great job and reasonably priced. Thank you James

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
