• Q: How to install the throttle with Throttle Body assembly on 2009 Toyota Yaris?

  A: The first step to install the throttle with motor body assembly on the 1NZ-FE engine control system requires placing a new gasket onto the intake manifold. The throttle with motor body assembly needs to be secured with a bolt along with three nuts to achieve the torque specification of 9.0 Nm (92 kgf-cm, 80 in-lbf). The next step involves attaching the water filler sub-assembly along with its hose using 2 nuts that require 7.5 Nm torque. After that, install the wire harness with bracket utilizing a nut torqued to 9.0 Nm. The installation continues with attaching motor body assembly connector to the throttle before adding Water by-pass hose No. 2 and water by-pass hose to the system. Secure the air cleaner cap sub-assembly through air cleaner hose No. 1 by tightening its clamp to an torque of 3.0 Nm (31 kgf-cm, 27 in-lbf). The procedure includes connecting the wire harness clamp and mass air flow meter connector followed by ventilation hose No. 2 and the vacuum switching valve assembly connector and wire harness clamp. The installation process ends with the connection of fuel vapor feed hose No. 1 and No. 2 to the vacuum switching valve assembly followed by cable connection with a torque of 5.4 Nm (55 kgf-cm, 48 in-lbf) to the negative battery terminal. Engine coolant addition must then be followed by leak checking.
