Lambda Control

Quality lambda control for your car from well-known brands. The lambda control (probe) is a small part in the car and is designed to ensure the efficient operation of the exhaust system. Also known as an oxygen sensor, a lambda probe is used to make the catalytic converter work better - the better it works, the fewer harmful particles it emits.

How to recognise a fault in the lambda probe?

Lambda probes operate in quite aggressive conditions - their sensors are constantly exposed to hot exhaust gases, so the sensor is exposed to extremely high temperatures, humidity and vibrations. Over time, exposure to these factors can lead to sensor failure, which can be caused by wear and tear, contamination or mechanical damage. Lambda probes should be checked and serviced regularly, and it is recommended that this check is carried out every 30,000 kilometres. Typically, probes can withstand mileage of up to 150 000 km or more. However, wear and tear and failure are inevitable over time. 

What are the main signs of failure?

- the "check engine" light on the dashboard comes on;

- loss of engine power;

- black smoke emissions;

- increase in fuel consumption;

- increased levels of carbon oxides and hydrocarbons in the exhaust gases

How to replace the lambda sensor?

If your mechanic has detected damage to the lambda sensor, replacement is inevitable. Lambda probes are not repaired or refurbished, so they are replaced regardless of the existing fault. There is no universal Lambda probe that fits all cars, so it must be selected for your specific car model. You can also buy a probe yourself at, where you can quickly find the right part for your car model using the convenient search engine. The price of a Lambda probe depends on the model and manufacturer of your car. You can buy the probe yourself or have it replaced by a professional technician, the cost of replacement is not very high. You will not be able to replace the probe yourself without the knowledge and parts you need. The technician will need to determine exactly where the probe is located in your car and where the probe connector is. Replacement also requires a special tool and high-temperature lubricant, which is supplied by the sensor manufacturer.
