ELTA have worked extensively to develop one of the UK’s leading ranges of Lambda (O2) Sensors. It now boasts over 400 Lambda Sensors for more than 3750 applications and covering 12.6 million vehicles on the road.

All are manufactured to the highest standards and are 100% tested to ensure operation within the manufacturer’s original parameters for clean efficient combustion.

Lambda sensors (also known as O2 sensors) operate by measuring the amount of oxygen in the exhaust. An efficient engine requires a specific amount of air and fuel in its cylinders at combustion. The perfect ratio being 14.7:1 (14.7 parts air to 1 part fuel.) This perfect mixture is called Lambda. The levels calculated by the Lambda are sent to the ECU which then determines how best to achieve the ideal ratio.
