A minimum of 90 seconds of negative battery terminal cable disconnect is necessary before servicing the Air Fuel Ratio Sensor for Bank 1 Sensor 1 to avoid Air Bag and seat belt pretensioner activation. Disengage the sensor from its manifold position through sensor connector removal followed by the utilization of Special Service Tool: 09224-00010 for sensor extraction. The exhaust manifold requires the sensor installation using Special Service Tool: 09224-00010 to insert the sensor properly with 40 N.m (408 kgf.cm, 30 ft.lbf) torque achieved using the tool or 44 N.m (449 kgf.cm, 32 ft.lbf) achieved without using the tool by using a torque wrench with a 30 cm (11.81 in.) fulcrum length. The sensor connector must be connected then you should reinstall the negative battery cable followed by system initialization because some systems need this procedure after battery detachment and reconnection. Exhaust gas leaks need to be inspected as the final step.
