Toyota Venza Service Manual / 1ar-fe Fuel / Fuel Injector / Inspection

INSPECTION

PROCEDURE

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 - 2	20°C (68°F)	11.6 to 12.4 Ω

If the result is not as specified, replace the fuel injector assembly.

(b) Inspect the injector injection.

CAUTION:

Keep the injector away from sparks during the test.

(1) Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).

(6) Put the fuel injector assembly into a graduated cylinder.

(7) Operate the fuel pump (See page ).

(8) Connect SST (wire) to the fuel injector assembly and the battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each fuel injector assembly 2 or 3 times.

Standard Injection Volume:

Tester Connection	Condition	Specified Condition
Positive terminal - Ground terminal	Per 15 seconds	88 to 106 cc (5.4 to 6.5 cu. in.)

Standard difference between each fuel injector assembly:

18 cc (1.1 cu. in.) or less

If the result is not as specified, replace the fuel injector assembly.

(1) In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel drop from the fuel injector assembly.

Standard fuel drop:

1 drop or less per 20 minutes

If fuel drop is not as specified, replace the fuel injector assembly.
