Oxygen Sensor: Service and Repair
REPLACEMENT OXYGEN SENSORThe oxygen sensor is a device which controls the fuel mixture. If the oxygen sensor is damaged, the exhaust-gas cleaning effect as well as driveability deteriorates. Therefore, its performance should be checked periodically using the O2 sensor monitoring function of the scan tool and replaced as necessary.
