2001 Toyota Sienna Parts Questions & Experts Answers

• Q: How to service and repair the throttle body on 2001 Toyota Sienna?

  A: Service and repair of the throttle body starts with draining engine coolant since it is the first step. You should remove the V-bank cover by first using a 5 mm hexagon wrench to undo the 3 cap nuts while counterclockwise turning the V-bank cover fastener until safely removing the cover. The servicing begins with disconnecting the PCV hose alongside the VSV for active engine control mount vacuum hose followed by unhinging the 3 hose clamps for removing the air cleaner hose with attached resonator. Detach the accelerator cable and throttle cable after which you should separate the throttle body from the throttle body bracket by using 19.5 N.m (200 kgf.cm, 14 ft.lbf) torque. Remove all components starting from the throttle position sensor connector and IAC valve connector, wire clamp as well as water bypass hoses from both the intake manifold and water inlet housing, air assist hose, fuel vapor feed hose from the emission control valve set and vacuum hoses from No.1 ACIS VSV and vacuum tank for ACIS. Apply new gasket to the air intake chamber of the throttle body before reinstalling its mounting nuts while tightening them to 29 N.m (300 kgf.cm, 22 ft.lbf). Installation requires performing all actions in the opposite sequence of removal steps.
