• Q: How to service and repair the throttle body on 2007 Toyota Prius?

  A: The first step for repairing or servicing the throttle body consists of disconnecting the negative battery cable while waiting at least 90 seconds to avoid Air Bag and seat belt pretensioner activation. The first step begins with removing the engine under cover LH while drainage of engine coolant occurs before removing the radiator support opening cover by uninstalling the 6 clips. The first step toward air cleaner assembly removal requires users to disconnect the MAF meter connector and wire harness clamp and loosen the hose clamp bolt to detach the No.1 air cleaner inlet and remove two bolts and separate the air cleaner through a clamp bolt release process. Remove the throttle body assembly with motor by disconnecting all components including ventilation hoses, No. 1 fuel vapor feed hose, water by-pass hoses, throttle control motor connector, throttle position sensor connector, and then removing the bolt with 2 nuts before taking off the throttle with motor body and removing its intake manifold gasket. Proceed with installing the new gasket on the intake manifold before using the bolt and 2 nuts to fasten the throttle with motor body at 20 N.m (204 kgf.cm, 15 ft.lbf). Reconnect the throttle position sensor and throttle control motor connectors followed by attaching the water by-pass hoses and fuel vapor feed hose. You should install the air cleaner assembly by tightening its 2 bolts to 7.0 N.m (71 kgf.cm, 62 in.lbf) before securing hose clamp bolts to 3.0 N.m (31 kgf.cm, 27 in.lbf) and reconnecting the MAF meter connector. Add engine coolant while attaching the cable to the negative battery terminal and inspect for leaks then reattach the engine under cover LH together with the radiator support opening cover using its 6 clips. A system initialization step must be done following cable disconnect and reconnect from the negative battery terminal during certain procedures.
