Tacoma Extra Cab 2WD V6-3.4L (5VZ-FE) (1998)
Fuel Injector: Testing and Inspection
INSPECTION
1. INSPECT INJECTOR RESISTANCE
Using an ohmmeter, measure the resistance between the terminals.
Resistance:
Approx. 13.8 ohms 20°C (68°F)
If the resistance is not as specified, replace the injector.
2. INSPECT INJECTOR 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 0926-41046 (09268-52011)
(c) Connect the fuel return hose, SST (union) and SST (hose) to the fuel pressure regulator.
SST 09268-41046 (09268-41091)
(d) Install the O-ring to the injector.
(e) Connect SST (union and hose) to the injector and hold the injector and union with SST (clamp).
SST 09268-41046
(f) Put the injector into the graduated cylinder.
HINT: Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out.
(g) Connect the TOYOTA hand-held tester to the DLC3. (See on-vehicle inspection in fuel pump)
(h) 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.
