2009 Toyota Sequoia Parts Questions & Experts Answers

• Q: How to install the throttle body assembly on 2009 Toyota Sequoia?

  A: The installation of the 2UZ-FE engine throttle body assembly requires the application of a new gasket and the use of 3 bolts and a nut to fasten the assembly with 14 Nm (143 kgf-cm, 10 ft-lbf) torque. Install the throttle body assembly connector before securing both 2 water by-pass hoses. Attach the air cleaner hose assembly with two clamps while torquing them to 4.0 Nm (41 kgf-cm, 35 in-lbf). It is essential to align the clamp band with the limit mark when tightening. Join the vacuum hose with the No. 2 ventilation hose together. Engine coolant should be added while performing a leak inspection. Shackle down the throttle body cover sub-assembly using 2 nuts while torquing them to 7.5 Nm (76 kgf-cm, 66 in-lbf). You must wait at least 60 seconds while the fuses remain disconnected beginning at the same time for EFI and ETCS fuses before reconnecting them. Turn the ignition ON while avoiding any pedal operation; perform the procedure again if the pedal is activated. Connect the Techstream to the DLC3 before clearing the stored DTCs. Before starting the engine the technician should verify that the MIL does not come on and that idle speed stays within the allowed range while the A/C remains off after the engine reaches its operating temperature while all accessories should be disabled and the shift lever set to N or P. Then navigate to Powertrain/Engine/Data List/Throttle Position Sensor Output in the menus and fully depress the accelerator pedal before ensuring the value exceeds 60%. A road test should be conducted to check for abnormal behavior.
