J 39194-C Oxygen Sensor Wrench
Important: Bank 1 are cylinders 1, 3, and 5 which are closest to the front of the dash.
Caution: Removal of the sensor is easier if the exhaust system is warmed up slightly. Be careful that it is not too hot to work on safely. Applying penetrating oil to the threads while moving the sensor back and forth will also aid in removal and will decrease the chance of exhaust pipe thread damage.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the oxygen sensor to 44 N·m (33 lb ft).
