Porsche Oxygen O2 Lambda Sensor Fuel and Fuel Injection : SensorsProduct InfoSensor Oxygen Porsche Oxygen O2 Lambda Sensor Part No: 91160612300Quantity: Invalid Quantity. Special Notes We have original Bosch Oxygen Sensors (O2 Sensors). They should be replaced when the red light comes on in the dashboard. The oxygen sensor detects the air-fuel mixture of a gasoline engine by measuring the amount of oxygen in the exhaust gas. The fuel-injection system will trim the mixture richer or leaner based on the signal from the oxygen sensor. I faulty Oxygen Sensor will cause a rough idle and poor fuel economy.
