This oxygen sensor plays a vital role in monitoring the amount of unburned oxygen in the exhaust gases. By accurately measuring oxygen levels, the engine control unit (ECU) can precisely adjust the air-fuel mixture to ensure efficient combustion. Proper functioning of the Lambda zonde is essential for reducing harmful emissions, improving fuel economy, and maintaining smooth engine operation. A faulty sensor can lead to increased fuel consumption, poor engine performance, and illuminated check engine lights. DENSO is a trusted manufacturer known for its high-quality automotive components.
