- J 39194-B Heated Oxygen Sensor Wrench

Removal Procedure





Important: The rear exhaust pipe and catalytic converter are only serviced as an assembly; components are not serviced separately.

1. Remove the exhaust crossover pipe.





Important: The heated oxygen sensor (HO2S) 2 uses a permanently attached pigtail and connector. This pigtail should not be removed from the sensor. Damage or removal of the pigtail or connector will affect proper operation of the sensor.

2. Remove HO2S 2 using the J 39194-B.





3. Remove the 2 bolts and 1 exhaust pipe nut at the manifold.
4. Remove the nuts at the outlet of the catalytic converter to crossover pipe.
5. Inspect the exhaust pipe-to-exhaust manifold flange.
