Air Fuel Ratio Sensor
REMOVAL1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
NOTE:
- Some systems need to be initialized after the cable is reconnected.
- After the ignition switch is turned OFF, the navigation system requires approximately 90 seconds to record various types of memory and settings. As a result, after turning the ignition switch OFF, wait 90 seconds or more before disconnecting the cable from the negative (-) battery terminal.

INSTALLATION
1. INSTALL AIR FUEL RATIO SENSOR (for Bank 1 Sensor 1)
a. Using SST, install the sensor.
SST 09224-00010
Torque: without SST 44 N.m (449 kgf.cm, 32 ft.lbf) with SST 40 N.m (408 kgf.cm, 30 ft.lbf)
HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). If using a torque wrench with a length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification.
- Make sure SST and wrench are connected in a straight line.
2. INSTALL AIR FUEL RATIO SENSOR (for Bank 2 Sensor 1)
a. Using SST, install the sensor.
SST 09224-00010
Torque: without SST 44 N.m (449 kgf.cm, 32 ft.lbf) with SST 40 N.m (408 kgf.cm, 30 ft.lbf)
HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). If using a torque wrench with a length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification.
- Make sure SST and wrench are connected in a straight line.
