• Q: How to replace the throttle body on 2005 Toyota Matrix?

  A: Start replacement of the throttle body by disconnecting the negative terminal from the battery and draining the engine coolant before proceeding. Remove the cylinder head cover No. 2 requiring unfastening of 2 nuts and 2 clips. Begin by disconnecting the mass air flow connector and VSV connector accompanied by the 2 wire clamp releases next to removing the fuel vapor feed hoses No. 1 and No. 3 from the VSV and ventilation hose No. 1 from the cylinder head cover. Unfasten the hose clamp bolt and air cleaner Hose No. 1 and afterward eliminate the air cleaner cap which includes the hose. You should detach the connecter of the throttle control motor as well as disconnect both water bypass tubes from the throttle body before uninstalling the throttle body's 2 bolts and 2 nuts to extract it while discarding its intake manifold gasket. Attach the throttle body to the intake manifold by using the 2 bolts and 2 nuts with a torques setting of 9.0 N.m (90 kgf.cm, 80 in.lbf). Connect the throttle control motor connector alongside both water by-pass hoses. To reinstall the air cleaner cap sub-assembly fit it in place with air cleaner hose before tightening the clamp bolt and attaching the hose which should be torqued to 2.0 N.m (20 kgf.cm, 18 in.lbf). Begin by installing ventilation hose No. 1 to the cylinder head and proceed with installing fuel vapor feed hoses No. 3 and No. 1 while attaching the VSV. Place the 2 wire harness clamps, then reconnect VSV and mass air flow meter connectors. The battery negative terminal requires reinstallation with a torque setting of 5.4 N.m (55 kgf.cm, 48 in.lbf) before filling the engine with coolant and testing for leakage. The work ends with installation of the cylinder head cover No. 2 using 2 nuts and 2 clips torqued to 7.0 N.m (71 kgf.cm, 62 in.lbf).
