The Lambda zonde, also known as an oxygen sensor, plays a crucial role in your vehicle's emissions control system. It measures the amount of unburned oxygen in the exhaust gases and sends this data to the engine control unit (ECU). By accurately reading oxygen levels, the ECU can adjust the air-fuel mixture for optimal combustion. This ensures efficient fuel economy and reduces harmful emissions. A malfunctioning Lambda zonde can lead to poor performance, increased fuel consumption, and a failed emissions test.
