The lambda sensor – also known as an ‘oxygen sensor’ – operates by monitoring and measuring the quantity of oxygen in the exhaust. Improving the efficiency of the combustion engine, the Lambda Sensor determines the levels of oxygen and sends the information in data format to the Engine Control Unit (ECU). The system can then calculate how much air and fuel is needed in the combustion mix to lower emissions while being able to retain optimum performance.
Lambda sensors are designed to operate in extremely hostile environments, coming in contact with corrosive exhaust gases and extreme temperatures. A sudden increase in fuel consumption, misfiring, or the engine experiencing a rough idle are common signs of lambda sensor failure. If the sensor is faulty, it is likely to cause the air/ fuel ratio to become imbalanced, affecting fuel economy. Another symptom of failure is when the Engine light appears lit on the dashboard.
It is advised that the sensor’s function is checked every 20,000 miles or annually, and an inspection is highly recommended when the exhaust system is repaired. If changing a catalytic converter, it is recommended that the lambda sensor is also replaced.
