Sensors are located before and after the catalytic converter to check on the amount of oxygen in the exhaust. The sensor sends signals to the car’s on-board computer, which then can adjust several variables, including air/fuel ratio and timing, in order to bring the engine into the optimum operating range.Each NTK Oxygen (O2) Sensor isExtensively Tested During Manufacture to Guarantee Quality and ReliabilitySupplied With a Factory-Fitted OEM Connector for Easy InstallationPrecision manufactured with a sensing element incorporating NTK’s premier technical ceramicsOxygen (O2) Sensors should be tested at each tune-up. Failed or worn out oxygen sensors can causeFailed Emission TestsIncreased Fuel ConsumptionFailed Catalytic ConvertersPoor DriveabilityIncreased Emissions
