2009 Toyota Sienna Throttle Body Parts Q&A

• Q: How to remove the throttle body on 2009 Toyota Sienna?

  A: Before extracting the throttle body from the 2GR-FE engine control system start by detaching the windshield wiper motor assembly followed by the removal of the front outer cowl top panel sub-assembly. The first task consists of draining engine coolant before proceeding with V-bank cover sub-assembly extraction. Start by taking off the No. 2 air cleaner inlet and then proceed to the No. 1 air cleaner inlet removal. When servicing the air cleaner cap sub-assembly disconnect the 3 vacuum hoses while removing the No. 2 ventilation hose alongside the air cleaner hose band before detaching the EVAP vacuum hose from the air cleaner hose and removing the mass air flow meter connector and the 2 bolts securing the assembly in place. Remove the air cleaner case sub-assembly following other steps. The final step to remove the throttle body requires disconnecting the throttle body connector and clamp, disconnecting 2 water by-pass hoses, removing 4 bolts from the throttle body and removing the throttle body gasket from the intake air surge tank.
