Oxygen sensors measure the amount of unburned oxygen in the exhaust stream, providing vital feedback for the ECU to adjust the air-fuel mixture in real-time for optimal combustion and catalytic converter efficiency. Faulty sensors lead to poor fuel economy, increased emissions, and potential catalyst damage. Our oxygen sensors offer fast response times and accurate readings across their operational lifespan. They enable precise fuel mixture control, helping engines run efficiently, meet emission standards, and maintain performance while protecting downstream exhaust components.
