Removing

Hybrid vehicles have a high voltage system! Danger of electrical shock! Visually inspect all of the high voltage components throughout the working area before starting work. Follow all general warnings.

- Remove the engine compartment cover. Refer to => [ Engine Compartment Cover ] Service and Repair.

- Disconnect the electrical connector - 4 - for the heated oxygen sensor 2 and free up the wire.

Installing

Installation is carried out in the reverse order while noting the following:

• Lubricate new oxygen sensors with an assembly paste. The paste must not get onto the slits in the sensor body.

• On a used oxygen sensor, only lubricate the threads with hot bolt paste. The paste must get into the slits in the sensor body. For the correct hot bolt paste, refer to the Parts Catalog.

• The oxygen sensor wire must always be attached at the same location when installing. This prevents the electric wire from touching the exhaust pipe.

• Tightening specification, refer to => [ Oxygen Sensor Overview ] Oxygen Sensor Overview.
