What is a Lambda Sensor?

Sometimes called car oxygen sensors, lambda sensors are a part of your vehicle's exhaust system. They work by measuring the amount of air and fuel in the unburnt hydrocarbons after the combustion. This information is then fed back to the ECU, which adjusts the amount of fuel so that only the required amount is used. In this way, the car oxygen sensor ensures that your vehicle complies with emissions regulations.

First introduced in the 1970s to help improve the efficiency of car engines, lambda sensors are used in both petrol and diesel vehicles. Many modern cars even have two. Here at GSF Car Parts, we have an extensive selection of sensors to suit all makes and models, including Vauxhall and Ford lambda sensors.
