Oxygen sensors play a critical role in monitoring the air-fuel mixture by detecting oxygen levels in the exhaust gases and sending signals to the engine control unit. A properly functioning oxygen sensor helps maximize fuel economy, reduce harmful emissions, and extend catalytic converter life. As the inventor of the automotive oxygen sensor in the late 1960s, Bosch continues to lead the industry in sensor technology and is the number one choice of carmakers worldwide.
