Heated Oxygen Sensor (HO2S) is equipped with a permanent pigtail which must be protected when oxygen sensor is removed. Oxygen sensor may be difficult to remove when engine temperature is less than 120°F (48°C). If necessary use a penetrant to help in loosening oxygen sensor. Ensure oxygen sensor is free of contaminants, and avoid using cleaning solvents of any type. Always use anti-seize compound on threads prior to installation. Tighten oxygen sensor to specification.
