2006 Scion xA Fuel Injector Parts Q&A

• Q: How to service and repair the fuel injector on 2006 Scion xA?

  A: Service and repair operations of the fuel injector begin by executing the following procedure: first remove the circuit opening relay (marked C/OPN) from the instrument panel junction block and start the engine until it stops and then turn the ignition switch OFF to check for engine start. The system must breathe through an open fuel tank cap alongside battery terminal disconnection for 90 seconds to block the Air Bag and seat belt pretensioner activation. Start by eliminating the 4 nuts and the No. 2 cylinder head cover from the sequence followed by removal of the ignition coil and the cylinder head cover sub-assembly. To disconnect the fuel tube sub-assembly use Special Service Tool: 09268-21010 while cleaning the connector first and applying a plastic bag for covering the disconnected pipe and connector. The fuel delivery pipe assembly removal starts with deconnecting 4 fuel injector connectors then three bolt removal and precise withdrawal of the combined fuel delivery pipe with 4 fuel injectors before extracting 2 spacers from the cylinder head. Pay attention to the 4 fuel injectors situated on the delivery pipe when replacing O-rings and insulators. Installation requires new insulators on each fuel injector with light grease or gasoline application to new O-rings then fuel injector insertion into the delivery pipe without rotating O-ring position. Install the 2 spacers on the cylinder head followed by the fuel delivery pipe with the 4 fuel injectors and torque bolt A to 19 N.m (194 kgf.cm, 14 ft.lbf) and bolt B to 9.0 N.m (194 kgf.cm, 14 ft.lbf) until finished connect the 4 fuel injector connectors. Check for any damage on the fuel tube and clear foreign objects before connecting its components with proper alignment of the tube to the pipe until a connecting "click" sound occurs. After installation of the fuel pipe clamp place the cylinder head cover sub-assembly along with the ignition coil before reconnecting the negative battery terminal. Install the No. 2 cylinder head cover by tightening nuts marked A first then nuts marked B to 7.0 N.m (71 kgf.cm and 62 in.lbf). The system needs initialization steps after you reconnect the battery terminal which has a negative (-) charge.
