2006 Toyota Tundra Catalytic Converter Parts Q&A

• Q: How to replace the catalytic converter on 2006 Toyota Tundra?

  A: The first step when replacing a catalytic converter involves disconnection of the heated oxygen sensor located at Bank 1. The exhaust center pipe requires removal of four bolts and two springs before continuation of the procedure. Begin by removing two nuts which secure the RH front exhaust pipe after which both gaskets on the RH front exhaust pipe and exhaust pipe need extraction. First disconnect Unit 2 heated oxygen sensor wiring connector and pull out the sensor from its position. The LH front exhaust pipe requires the removal of 2 nuts and the exhaust pipe support while dismantling the pipe completely together with its 2 gaskets. First disconnect A/F sensor connector for Bank 1 before you remove the 6 bolts and 2 manifold stays together with the sensor. Removing the exhaust manifold RH consists of uninstalling its 6 nuts and removing the manifold together with the gasket. Perform the same steps for the A/F sensor (Bank 2) while disconnecting its connector followed by removing the sensor. Then move to the exhaust manifold LH by taking off its 6 nuts and the manifold together with the gasket. Relay the exhaust manifold RH with a new gasket while placing the oval shape forward and torque all 6 nuts to 21 N.m (214 kgf.cm, 15 ft.lbf). Affix the Bank 1 A/F sensor by torqueing it to 44 N.m (450 kgf.cm, 33 ft.lbf) and attach its sensor connector. The LH exhaust manifold installation requires a new gasket oriented correctly facing backward and torqueing of 6 nuts to 21 N.m (214 kgf.cm, 15 ft.lbf). Fasten the A/F sensor for Bank 2 with 44 N.m (450 kgf.cm, 33 ft.lbf) torque while connecting its sensor connector. The two manifold stays should be installed with six bolts that receive torque to 40 N.m (408 kgf.cm, 30 ft.lbf). The LH front exhaust pipe installation requires 2 new gaskets before attaching with 2 new nuts and torqueing them to 62 N.m (630 kgf.cm, 46 ft.lbf) along with exhaust pipe support installation. Attach Bank 2 heated oxygen sensor while torquing the fastener to 44 N.m (450 kgf.cm, 33 ft.lbf) then link the sensor connector. Apply 2 new gaskets to the RH front exhaust pipe and fasten it with 2 new nuts tightened to 62 N.m (630 kgf.cm, 46 ft.lbf). At the end of the installation, secure the Bank 1 heated oxygen sensor with 44 N.m torque while connecting its sensor connector. Use 2 bolts to connect the exhaust center pipe while torqueing to 48 N.m (489 kgf.cm, 35 ft.lbf) and proceed to install 2 bolts with springs and torque them to 43 N.m (440 kgf.cm, 32 ft.lbf).
