Heated Oxygen Sensor 2: Notes
WARNING: This page is about a different car, the 2003 Pontiac Grand Am and 2003 Oldsmobile Alero. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
The HO2S 2 uses a permanently attached pigtail and connector. Do not remove the pigtail from the HO2S. Damage to or removal of the pigtail connector could affect proper operation of the oxygen sensor. The use of excessive force may damage the threads in the exhaust manifold. The in-line connector and louvered end must be kept clear of grease, dirt or other contaminants. Avoid using cleaning solvents of any type. Do not drop or roughly handle the oxygen sensor. The oxygen sensor may be difficult to remove when the engine temperature is less than 120°F (48°C).
NOTE:
Heated Oxygen Sensor 2 (HO2S 2) may also be referred to as Heated Oxygen Sensor Bank 2.
