2000 Toyota Sienna Parts Questions & Experts Answers

• Q: How to service and repair the throttle body on 2000 Toyota Sienna?

  A: The first step for servicing and repairing the throttle body includes draining the engine coolant. You need to disconnect the hose from the air cleaner cap by unhooking the MAF meter connector as well as the EVAP hose from the charcoal canister and PCV hose from the cylinder head cover. Unclip the two retaining clamps to extract the air cleaner cap from its mjount on the air cleaner case. Separately release the hose clamp for unhinging the throttle body connection with the air cleaner hose before removing the air cleaner cap option along with its hose. As the next step disconnect both the accelerator cable and throttle cable. The removal process for the throttle body requires disconnecting the throttle position sensor connector and IAC valve connector together with three hose connections: water bypass hose from both the intake manifold and water inlet housing and air assist hose. Two bolts along with two nuts must be removed to disconnect the throttle body from its gasket. The technician should apply a new gasket to the air intake chamber before tightening bolts to 19.5 Nm (200 kg.cm, 14 ft.lb). The installation sequence for this operation reverses the order used for disconnect.
