Tundra 2WD V6-3.4L (5VZ-FE) (2004)
Fuel Injector: Testing and Inspection
INSPECTION
1. INSPECT INJECTOR RESISTANCE
Using an ohmmeter, measure the resistance between the terminals.
Resistance: 13.4 - 14.2 Ohm at 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 09268-41047 (09268-52011)
c. Connect the fuel return hose, SST (union) and SST (hose) to the fuel pressure regulator.
SST 09268-41047 (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 09268-41047
f.
Put the injector into the graduated cylinder.
