SF0D6–04 –SFI (5S–FE) SFI SYSTEM SF–1 1434AuthorĂ: DateĂ: SFI SYSTEM PRECAUTION 1. BEFORE WORKING ON FUEL SYSTEM, DISCON- NECT NEGATIVE (–) TERMINAL CABLE FROM BAT- TERY HINT: Any diagnostic trouble code retained by the computer will be erased when the negative (–) terminal cable is removed from the battery. Therefore, if necessary, read the diagnosis before removing the negative (–) terminal cable from the battery. 2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME WHEN WORKING ON THE FUEL SYSTEM 3. KEEP GASOLINE AWAY FROM RUBBER OR LEATH- ER PARTS 4. MAINTENANCE PRECAUTIONS (a) In event of engine misfire, these precautions should be taken. (1) Check proper connection to battery terminals, etc. (2) After repair work, check that the ignition coil termi- nals and all other ignition system lines are recon- nected securely. (3) When cleaning the engine compartment, be espe- cially careful to protect the electrical system from water. (b) Precautions when handling the oxygen sensor. (1) Do not allow oxygen sensor to drop or hit against an object. (2) Do not allow the sensor to come into contact with water. 5. IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYS- TEM (HAM, CB, ETC.) If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section. 6. AIR INDUCTION SYSTEM (a) Separation of the engine oil dipstick, oil filler cap, PCV hose, etc. may cause the engine to run out of tune. (b) Disconnection, looseness or cracks in the parts of the air induction system between the throttle body and cylinder head will allow air suction and cause the engine to run out of tune. 7. ELECTRONIC CONTROL SYSTEM (a) Before removing SFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition switch OFF or disconnecting the negative (–) terminal cable from the battery. HINT: Always check the diagnostic trouble code before disconnecting the negative (–) terminal cable from the battery. FI2553 SST S04600 Fuel Pump Connector S05326 Plug SF–2 –SFI (5S–FE) SFI SYSTEM 1435AuthorĂ: DateĂ: (b) When installing the battery, be especially careful not to in- correctly connect the positive (+) and negative (–) cables. (c) Do not permit parts to receive a severe impact during re- moval or installation. Handle all SFI parts carefully, espe- cially the ECM. (d) Be careful during troubleshooting as there are numerous transistor circuit, and even slight terminal contact can cause further troubles. (e) Do not open the ECM cover. (f) When inspecting during rainy weather, take care to pre- vent entry of water. Also, when washing the engine compartment, prevent water from getting on the SFI parts and wiring connectors. (g) Parts should be replaced as an assembly. (h) Care should be taken when pulling out and inserting wir- ing connectors. (1) Release the lock and pull out the connector, pulling on the connectors. (2) Fully insert the connector and check that it is locked. (i) Use SST for inspection or test of the injector or its wiring connector. SST 09842–30070 8. FUEL SYSTEM (a) When disconnecting the high fuel pressure line, a large amount of gasoline will spill out, so observe these proce- dures: (1) Disconnect the fuel pump connector. (2) Start the engine. After the engine has stopped on its own, turn the ignition switch OFF. (3) Put a container under the connection. (4) Slowly loosen the connection. (5) Disconnect the connection. (6) Plug the connection with a rubber plug. (7) Reconnect the fuel pump connector.

Before installing the injector, must apply spindle oil or gas- oline on the place where a delivery pipe or an intake man- ifold touches an O–ring of the injector. (f) Observe these precautions when disconnecting the fuel tube connector (quick type): (1) Check if there is any dirt like mud on the pipe and around the connector before disconnecting them and clean the dirt away. (2) Be sure to disconnect with hands. (3) When the connector and the pipe are stuck, pinch the retainer between the hands, push and pull the connector to free to disconnect and pull it out. Do not use any tool at this time. (4) Inspect if there is any dirt or the likes on the seal sur- face of the disconnected pipe and clean it away. (5) Prevent the disconnected pipe and connector from damaging and mixing foreign objects by covering them with a vinyl bag. (g) Observe these precautions when connecting the fuel tube connector (quick type): (1) Do not reuse the retainer removed from the pipe. (2) Must use hands without using tools when to remove the retainer from the pipe. (3) Check if there is any damage or foreign objects on the connected part of the pipe. S05050 Click Sound S05331 –SFI (5S–FE) SFI SYSTEM SF–5 1438AuthorĂ: DateĂ: (4) Match the axis of the connector with axis of the pipe, and push in the connector until the retainer makes a ”click” sound. In case that the connections is tight, apply little amount of new engine oil on the tip of the pipe. (5) After having finished the connection, check if the pipe and the connector are securely connected by pulling them. (6) Check if there is any fuel leakage. (h) Observe these precautions when handling nylon tube. (1) Pay attention not to turn the connected part of the nylon tube and the quick connector with force when connecting them. (2) Pay attention not to kink the nylon tube. (3) Do not remove the EPDM protector on the outside of the nylon tube. (4) Must not close the piping with the nylon tube by bending it. (i) Check that there are no fuel leaks after doing mainte- nance anywhere on the fuel system. (1) Connect a TOYOTA hand–held tester to the DLC3. (2) Turn the ignition switch ON and push the TOYOTA hand–held tester main switch ON. NOTICE: Do not start the engine. (3) Select the active test mode on the TOYOTA hand– held tester. (4) Please refer to the TOYOTA hand–held tester oper- ator’s manual for further details. (5) If you have no TOYOTA hand–held tester, connect the positive (+) and negative (–) leads from the bat- tery to the fuel pump connector. (See page SF–6) (6) Check that there are no leaks from any part of the fuel system. (7) Turn the ignition switch OFF. (8) Disconnect the TOYOTA hand–held tester from the DLC3.
