2008 Toyota Matrix Throttle Body Parts Q&A

• Q: How to service and repair the throttle body on 2008 Toyota Matrix?

  A: One must start servicing or repairing the throttle body for a 1ZZ-FE engine by first disconnecting the battery negative terminal. Remove the cylinder head cover No. 2 by detaching its 2 nuts and 2 clips while draining the engine coolant. Start by disconnecting the assembly parts of the air cleaner cap which includes the mass air flow meter connector [A], VSV connector [B], and the two clamps [C]. The first [D] and third [E] fuel vapor feed hoses and the ventilation hose No. 1 must be detached from the VSV for this procedure. Roll off the hose clamp bolt and disconnect air cleaner hose No. 1 to withdraw the air cleaner cap and hose assembly. The throttle body assembly removal process starts with removing two components - the throttle control motor connector along with water by-pass hose [B] and water by-pass hose No. 2 [C]. To end the procedure remove the throttle body gasket from the intake manifold after disconnecting its 2 bolts and 2 nuts.
