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

  A: The first step to remove the throttle body from the 1NZ-FE engine control system involves removing the negative battery cable. Before proceeding users should drain engine fluid followed by removal of the cylinder head cover Number 2. Uninstall the air cleaner cap sub-assembly with air cleaner hose number one after separating fuel vapor feed hoses of numbers one and two from the vacuum switching valve assembly and vacuum switching valve assembly connector and wire harness clamp and ventilation hose number two. Begin the procedure by disconnecting the wire harness clamp and mass air flow meter connector before loosing the hose clamp and unlocking the air cleaner assembly clamp and finally taking off the air cleaner cap sub-assembly with air cleaner hose No. 1. Drain the water by-pass hose as well as water by-pass hose No. 2. The process of taking off the throttle with motor body assembly begins with disconnecting its connector then removing the nut and wire harness with bracket before taking off the two nuts and the water filler sub-assembly with its attached hose. The procedure ends with bolt removal and three nut removal to separate the throttle with motor body assembly and extract its gasket from the intake manifold.
