SF20 SFI (5VZFE) SF02304 REMOVAL 1. REMOVE AIR CLEANER HOSE 2. REMOVE INTAKE AIR CONNECTOR ASSEMBLY (See page EM29 ) 3. REMOVE FUEL PRESSURE REGULATOR (See page SF16 ) 4. DISCONNECT FUEL INLET PIPE CAUTION: Catch leaking fuel in a container. 5. REMOVE FUEL PIPE 6. DISCONNECT CONNECTORS P21207 7. REMOVE DELIVERY PIPES AND S NOTICE: Be careful not to drop the injectors when removing the delivery pipes. Pay attention to put any hung load on the injector to and from the side direction. (a) Remove the 4 bolts and delivery pipes together with the 6 injectors. (b) Remove the 4 spacers from the intake manifold. (c) Pull out the 6 injectors from the delivery pipes. (d) Remove the 2 Orings and insulator from each injector. 949
Ohmmeter SFI (5VZFE) SF21 SF02404 INSPECTION 1. INSPECT RESISTANCE Using an ohmmeter, measure the resistance between the terminals. Resistance: Approx. 13.8 Ω at 20 C (68 F) If the resistance is not as specified, replace the injector. B06053 Pressure Regulator (from Vehicle) SST (Union) SST (Hose) Injector SST (Attachment) B06059 2. INSPECT INJECTION CAUTION: Keep injector clear of sparks during the test. (a) Disconnect the fuel inlet pipe from the fuel tube. (b) Connect SST (attachment and hose) to the fuel tube. SST 0926841047 (0926852011) (c) Connect the fuel return hose, SST (union) and SST (hose) to the fuel pressure regulator. SST 0926841047 (0926841091) Vinyl Tube SST (Hose) B06054 (d) Connect SST (hose) to the injector. SST 0926841047 (e) Put the injector into the graduated cylinder. HINT: Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out. (f) Connect a TOYOTA handheld tester to the DLC3. (See page SF7 ) SST (Wire) B06058 (g) Connect SST (wire) to the injector and battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times. SST 0984230070 Volume: 60 73 cm 3 (3.4 4.5 cu in.) per 15 sec. Difference between each injector: 13 cm 3 (0.8 cu in.) or less If the injection volume is not as specified, replace the injector. B06055 3. INSPECT LEAKAGE (a) In the condition above, disconnect the tester probes of SST (wire) from the battery and check the fuel leakage from the injector. SST 0984230070 Fuel drop: 1 drop or less per 12 minutes (b) Turn the ignition switch OFF. (c) Disconnect the negative () terminal cable from the battery. 950
SF22 SFI (5VZFE) (d) (e) Remove the SST. SST 0926841047 Disconnect the TOYOTA hand held tester from the DLC3. 951
New Insulator New ORing SFI (5VZFE) INSTALLATION SF23 SF02504 1. TEMPORARILY INSTALL S AND DELIVERY PIPES (a) Install a new insulator to each injector. (b) Apply a light coat of spindle oil or gasoline to 2 new O rings and install them to each injector. New ORing B06056 Connector Turn (c) (d) While turning the injector clockwise and counterclockwise, push it to the delivery pipes. Install the 6 injectors. Position the injector connector outward. Push B06065 (e) (f) (g) Place the 4 spacers in position on the intake manifold. Place the delivery pipes with the 6 injectors in position on the intake manifold. Temporarily install the 4 bolts holding the delivery pipes to the intake manifold. P21208 Connector Rotate Outward (h) Check that the injectors rotate smoothly. HINT: If injectors do not rotate smoothly, the probable cause is incorrect installation of Orings. Replace the Orings. (i) Position the injector connector outward. P21216 P21207 2. CONNECT CONNECTORS 3. INSTALL FUEL PIPE AND TIGHTENING DELIVERY PIPE HOLDING BOLTS (a) Install the fuel pipe with 4 new gaskets and the 2 union bolts. Torque: 34.3 N m (350 kgf cm, 25 ft lbf) (b) Tighten the 4 bolts holding the delivery pipes to the intake manifold. Torque: 13 N m (130 kgf cm, 10 ft lbf) 952
SF24 SFI (5VZFE) P21209 4. CONNECT FUEL INLET PIPE (a) Temporarily install the inlet pipe with 2 new gaskets, union bolt and bolt. (b) Tighten the clamp bolt. Torque: 8 N m (80 kgf cm, 71 in. lbf) (c) Tighten the union bolt. Torque: 34.3 N m (350 kgf cm, 25 ft lbf) 5. INSTALL FUEL PRESSURE REGULATOR (See page SF17 ) 6. INSPECT AIR ASSIST LINES AND CONNECTIONS Visually check for loose connections, sharp bends or damage. 7. INSTALL INTAKE AIR CONNECTOR ASSEMBLY (See page EM52 ) 8. INSTALL AIR CLEANER HOSE 9. CHECK FOR FUEL LEAKS (See page SF1 ) P21217 953
