Oxygen Sensor: Notes

Oxygen sensor uses a permanently attached pig-tail and connector. The pig-tail should not be removed from sensor. Damage or removal of pig-tail or connector could affect proper operation of sensor. Care must be taken when handling sensor.

The in-line electrical connector and louvered end must be kept free of grease or other contaminants. Do not use cleaning solvents of any type. Sensor may be difficult to remove when engine temperature is below 120°F (48°C). Excessive force may damage threads in exhaust manifold or pipe.
