• Q: How to replace the throttle body on 2006 Toyota Corolla?

  A: The replacement of throttle bodies begins with the removal of battery negative terminal power and engine coolant draining. The process requires removing head cover No. 2 by unfastening two retention clips and two nuts. You must begin with air cleaner cap assembly removal. Start disconnecting the mass air flow meter connector then follow with removing the VSV connector. Then detach both wire harness clamps followed by disconnecting fuel vapor feed hoses No. 1 and No. 3 connected to the VSV and the ventilation hose No. 1 from the cylinder head cover. Tenoncesh the air condenser hose No. 1 by removing its clamp bolt while you slide off the connected air cleaner cap and hose from the assembly. The installer should disconnect throttle body accessories beginning with the throttle control motor connector followed by removing both water by-pass hoses from the throttle body before uninstalling it from the intake manifold with 2 bolts and 2 nuts. Before installing place a new gasket onto the intake manifold then mount the throttle body attaching the 2 bolts and 2 nuts which require a torque of 9.0 Nm (90 kgf.cm, 80 in.lbf) before reattaching the water by-pass hoses together with the throttle control motor connector. Reinstallation of the air cleaner cap sub-assembly requires securing the hose clamp bolt and reattaching the air cleaner hose at 2.0 Nm torque (20 kgf.cm, 18 in.lbf) together with ventilating hose No. 1 repairs along with fuel vapor feed hoses No. 3 and No. 1 installation to the VSV and then installing the 2 wire harness clamps before connecting the VSV and mass air flow meter connectors. The maintenance sequence concludes with reattaching the negative battery terminal while tightening it to a torque of 5.4 Nm (55 kgf.cm, 48 in.lbf). Then add engine coolant followed by leak checkups before installing cylinder head cover No. 2 using its 2 nuts and 2 clips torqued to 7.0 Nm (71 kgf.cm, 62 in.lbf).
