Exhaust Manifold -- Installation |
1. INSTALL AIR FUEL RATIO SENSOR (for Bank 2 Sensor 1) |
Using SST, install the air fuel ratio sensor.
- SST
- 09224-00010
- Torque:
- without SST:

Text in Illustration *1 Fulcrum Length - HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum 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 (HILUX_TGN26 RM000004QR1006X.html).
- Make sure SST and the wrench are connected in a straight line.
