The service process for the Air-Fuel Ratio Sensor starts with battery cable removal from the terminal. Send the air fuel ratio sensor to removal by unplugging the air fuel ratio sensor connector and wire harness clamp followed by use of Special Service Tool: 09224-00010. To install the air fuel ratio sensor employ Special Service Tool: 09224-00010 and apply 44 N.m (449 kgf.cm, 33 ft.lbf) torque while using a 300 mm (11.81 in.) fitted torque wrench. Alternatively, use a torque of 40 N.m (408 kgf.cm, 30 ft.lbf) with the tool. Following installation you should link the air fuel ratio sensor to the connector and the wire harness clamp. Secure the negative battery cable with 3.9 N.m of torque using a 40 kgf.cm (35 in.lbf) configuration.
