Installing

• Tightening specifications, refer to => [ Installed Location: Oxygen Sensors (O2S) Behind
Three Way Catalytic Converter, Tightening Specification ] Component Location Overview.

Installation is in reverse order of removal, note the following:

• Coat new oxygen sensors with an assembly paste.

• When reinstalling the previously used oxygen sensor, coat thread with hot bolt paste.

• Assembly paste or hot bolt paste must not get on slits in sensor body.

• Electrical wire of oxygen sensor must always be secured in the same position when installing so that contact with the exhaust pipe is avoided.
