• Q: How to install the throttle body assembly on 2008 Toyota Sequoia?

  A: The installation of the throttle body assembly on the 2UZ-FE engine requires using a new gasket and requires securing three bolts and a nut with a torque setting at 14 Nm (143 kgf-cm, 10 ft-lbf). The throttle body assembly connector along with the 2 water by-pass hoses should be properly connected. The air cleaner hose assembly requires installation with two clamps tightened to 4.0 Nm (41 kgf-cm, 35 in-lbf) such that the clamp band end reaches the limit mark during tightening. Associate the vacuum tube with the No. 2 ventilation tube. Check the system for any detected leakage as you add the engine coolant. Screw two nuts into the throttle body cover sub-assembly while torquing them to 7.5 Nm (76 kgf-cm, 66 in-lbf). After performing throttle body reassembly or removing components and reconnecting the battery cable along with the ECM installation, safely disconnect EFI and ETCS fuses simultaneously before keeping fuses isolated for at least 60 seconds then reconnecting the fuses. Before operating the accelerator pedal, turn the ignition switch to ON. In case the pedal is depressed, begin the procedure again from start. Use the Techstream to connect to the DLC3 port to perform a DTCs clearing function. After engine warm-up start the engine while making sure the MIL stays dark and idle speed lies within its specified range using no A/C and disable all accessories while placing the shifter in N or P. Check the throttle output reading of 60% or more in the Powertrain/Engine/Data List/Throttle Position Sensor Output menu with the pedal fully depressed. After completing the test you must drive the vehicle to ensure no unusual conditions occur.
