• Q: How to service and repair the fuel injector on 2007 Toyota Camry?

  A: Service and repair of the fuel injector begins by emptying fuel system pressure and then disconnecting the negative battery cable terminal. The service starts with removal of the air cleaner cap sub-assembly and the No. 1 engine cover sub-assembly followed by disconnecting the fuel tube sub-assembly through No. 1 fuel pipe clamp removal and checking for foreign matter on both pipe and connector before detachment. To detach the stuck pipe and connector pinch the connection and gently move both parts apart. Avoid using tools on this process and cleanse any required sealing surfaces. The procedure requires removal of the fuel tube from the fuel hose clamp followed by disconnecting the No. 2 ventilation hose from the ventilation valve. Use two clamps on the wire harness to detach it before disconnecting the 4 fuel injector connectors and removing the 2 bolts to extract the fuel delivery pipe and its 4 fuel injectors with great caution to prevent drops. Extract the 2 delivery pipe spacers as well as the 4 insulators from the cylinder head before you remove the 4 injectors from the delivery pipe and detach the 4 O-rings. Before you install new O-rings you should apply a thin coat of gasoline or spindle oil to each part before mounting one onto each fuel injector and applying the oil to the fuel delivery pipe areas exposed to O-rings. When installing right and left fuel injectors onto the fuel delivery pipe ensure both the O-ring remains free of damage and check that fuel injectors can move smoothly before replacing any broken O-rings. Tighten up the 2 delivery pipe spacers after installing 4 new insulators inside the cylinder head and then mount the fuel delivery pipe containing the 4 fuel injectors temporarily. Maintaining caution about dropping the injectors tighten the bolts but only slightly. Leave the fuel injectors to rotate once more before refusing the 2 bolts to 20 N.m torque (204 kgf.cm, 15 ft.lbf) and establish the 4 fuel injector connectors with both wire harness clamps installed. Connect the No. 2 ventilation hose to the ventilation valve by ensuring an appropriate position for both paint mark and hose clamp. The fuel tube sub-assembly needs to be connected by installing the fuel tube through the fuel hose clamp then pushing the connector until it clicks followed by the No. 1 fuel pipe clamp installation protocol. Conclude the installation by connecting the cable to the negative battery terminal then checking for leaks before placing back the No. 1 engine cover sub-assembly.
