2010 Toyota Yaris Throttle Body Parts Q&A

• Q: How to install the throttle with Throttle Body assembly on 2010 Toyota Yaris?

  A: Before installing the throttle with motor body assembly on the 1NZ-FE engine control system you should position a new gasket onto the intake manifold. Use the bolt along with three nuts to secure the throttle with motor body assembly while tightening all three components to 9.0 Nm (92 kgf-cm, 80 in-lbf). Then attach the water filler sub-assembly with hose by torquing two nuts to 7.5 Nm (76 kgf-cm, 66 in-lbf). Lastly, connect the wire harness with bracket by torquing its own nut to 9.0 Nm (92 kgf-cm, 80 in-lbf). After connecting the throttle to its motor body assembly connector you should proceed with joining the water by-pass hoses No. 2 and 1. Fasten the air cleaner cap sub-assembly through air cleaner hose No. 1 while tightening the clamp to 3.0 Nm (31 kgf-cm, 27 in-lbf). Proceed by attaching the wire harness clamp to the mass air flow meter connector then connect ventilation hose No. 2 after which the vacuum switching valve assembly connector follows and finally the wire harness clamp. The vacuum switching valve assembly receives both fuel vapor feed hoses Number 1 and Number 2. Proceed by connecting the cable to the negative battery terminal and tightening it to 5.4 Nm (55 kgf-cm, 48 in-lbf) while adding engine coolant followed by leakage inspection and installation of cylinder head cover No. 2. The cleaning procedure or component installation for the throttle body requires the negative battery cable disconnection and a minimum 60-second wait period before reattachment. The ignition switch should be turned to ON while avoiding accelerator pedal operation; subsequent pedal operation requires the repetition of earlier procedures. Start the connection of the Techstream to the DLC3 to clear all stored DTCs. Verify that the engine starts up without MIL illumination along with proper idle speed within range after switching off the A/C when the engine reaches operating temperature. Please put both automatic transaxles and manual transaxles into neutral position with no accessories operating. Users should access Powertrain / Engine and ECT / Data List / Throttle Sensor Position through the menu after fully pressing the accelerator pedal to verify the value exceeds 60%. A complete road test should confirm any potential system irregularities after completing the procedure.
