• Q: How to install the throttle body assembly with motor on 2009 Toyota Prius?

  A: Installation of the throttle body assembly with motor on the 1NZ-FXE engine control system starts by applying a new gasket to the intake manifold. The throttle with motor body gets attached via a bolt secured with 2 nuts that require 20 Nm (204 kgf-cm, 15 ft-lbf) torque for fixation. The installation requires connecting the throttle position sensor connector alongside the throttle control motor connector and No. 2 water by-pass hose as well as the water by-pass hose and No. 1 fuel vapor feed hose followed by attachments of the No. 2 ventilation hose and the ventilation hose. The air cleaner assembly needs 2 bolts for installation where each torque reaches 7.0 Nm (71 kgf-cm, 62 in-lbf), and the hose clamp bolt requires a torque of 3.0 Nm (31 kgf-cm, 27 in-lbf). Attach the No. 1 airflow inlet while tightening its hose clamp bolt to 3.0 Nm (31 kgf-cm, 27 in-lbf). After that, connect the MAF meter connector. Start by connecting the cable to the negative terminal then pour engine coolant before checking for coolant leakage points. Securely fit 6 clips to either install the engine under cover LH and the radiator support opening cover toward the front. The last stage involves system initialization since some systems demand this procedure after the cable disconnects from the negative (-) battery terminal.
