Q: How to service the Heated Oxygen Sensor for Bank 1 Sensor 1 on Scion xA?
A: The first step for servicing the Heated Oxygen Sensor for Bank 1 Sensor 1 includes disconnecting the negative battery cable followed by a 90-second wait prior to servicing to avoid Air Bag and seat belt pretensioner activation. Perform heated oxygen sensor servicing by using Special Service Tool: 09224-00010 to remove the sensor after disconnecting its sensor connector. The sensor must be installed with Special Service Tool: 09224-00010 according to the installation specifications which require a 44 N.m (449 kgf.cm, 32 ft.lbf) torque when using the tool or 40 N.m (408 kgf.cm, 30 ft.lbf). Utilize a torque wrench with a fulcrum length of 30 cm (11.81 in.). The sensor connector should be connected first before reconnecting the cable to the negative battery terminal and system initialization must be done due to post-battery-disconnect requirements. The last check involves leak testing for exhaust gases while tightening problem areas to prevent leaks. At the same time replace any broken parts.
Q: How to remove the heated oxygen sensor for Bank 1 Sensor 2 on Scion tC?
A: The removal process of the heated oxygen sensor for Bank 1 Sensor 2 in the 2AZ-FE emission control system begins by disconnecting the negative battery terminal cable while remembering potential system initialization requirements. The sensor connector needs removal followed by the usage of Service Tool: 09224-00010 to extract the sensor from the front exhaust pipe.
Q: How to install the heated oxygen sensor on Scion xB?
A: The installation of the heated oxygen sensor for the 2AZ-FE engine control system requires Special Service Tool: 09224-00010 to achieve proper sensor placement while torquing the sensor at 44 Nm (449 kgf-cm, 32 ft-lbf) followed by a subsequent torque of 40 Nm (408 kgf-cm, 30 ft-lbf). Special Service Tool: should be placed at a 30 mm (1.18 in.) length while using a torque wrench with 300 mm (11.81 in.) fulcrum length to achieve torque while orienting the Tools parallel to the wrench during installation. Users must install the heated oxygen sensor connector while checking for exhaust gas leaks in the system.
