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.

    Did a blinding job on my 2000 3.5 V6 Shogun facelift. Better idle and easier pull through the range and my mileage seems to have improved as well.

    Just had my Mitsubishi L200 tuned, needed that extra bit of pulling power when it's fully loaded, James came to my door and done the remap within an hour, had a quick drive around the town and can definitely feel the difference in pull through the revs, be interesting to see what sort of fuel consumption gains I'm going to get from this as well!! Top bloke and would recommend to anyone else.

    Had my wee car carbon cleaned today must admit I was a bit sceptical at first but glad I opted to get it done James was very polite and professional talks you through everything he is doing , went for a run in the car tonight and it is a lot quieter ,runs smother and would in my opinion have more power thanks James �

    James mapped my Cupra only on a stage 1 custom map and produced better BHP and the same torque as what the Revo stage 1 (£449) would produce but at over half the price. The dyno garage I took it too were extremely impressed to get these figures out punching a renowned name like Revo, faultless.

    Had my A5 carbon cleaned yesterday and I'm really impressed. It's a 13 plate with low mileage so I did the clean more for preventive reasons but I was surprised by the improvement I've felt in the drive. It's much smoother and it's pulling harder, particularly going from 2nd to 3rd. Matt is a professional but friendly guy and really knows what he's talking about. I will definitely get this done regularly now

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
