• Q: How to remove the throttle body on 2008 Toyota Sienna?

  A: The first step for throttle body removal from the 2GR-FE engine control system includes disconnecting the windshield wiper motor assembly along with the front outer cowl top panel sub-assembly. The first step involves draining engine coolant followed by V-bank cover sub-assembly removal and after that it is necessary to uninstall the No. 2 and No. 1 air cleaner inlets. Start by disconnecting three vacuum hoses from the air cleaner cap sub-assembly before removing the No. 2 ventilation hose and air cleaner hose band and disconnecting the EVAP vacuum hose from the air cleaner hose and disconnecting the mass air flow meter connector followed by unbolted the two securing bolts of the air cleaner cap sub-assembly. Next proceed to eliminate the air cleaner case sub-assembly. The throttle body requires removal by disconnecting its connector and clamp followed by unhinging the two water by-pass hoses and unscrewing four bolts that secure it before extracting the gasket from the intake air surge tank.
