  Q: How to service the Heated Oxygen Sensor for Bank 1 Sensor 2 on Scion xA?

  A:

  A proper servicing of the Heated Oxygen Sensor Bank 1 Sensor 2 requires disconnecting the negative battery terminal cable and waiting at least 90 seconds to stop Air Bag and seat belt pretensioner activation. To begin the heated oxygen sensor service on Bank 1 Sensor 2 you must remove the shift lever knob followed by the rear console box then disconnect the sensor connector before using Special Service Tool: 09224-00010. Installation of the new sensor requires Special Service Tool: 09224-00010 while torqueing it to 44 N.m (449 kgf.cm, 32 ft.lbf) using the tool but to 40 N.m (408 kgf.cm, 30 ft.lbf) without the tool when using a torque wrench with a 30 cm (11.81 in.) fulcrum length. The process ends when you reconnect the sensor connector followed by reinstallation of the rear console box and shift lever knob and cable reconnection to the negative battery terminal. System initialization should be performed after the battery disconnect due to system requirements. The process ends with exhaust gas leak checks to follow up repair of any damaged or loose components.

  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.
