Title: 2GR-FE FUEL: FUEL INJECTOR: INSPECTION; 2016 MY Sienna [12/2015 - 08/2016]

INSPECTION

PROCEDURE

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) Check the resistance.

Component without harness connected

(Fuel Injector Assembly)

(1) 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 injector assembly.

(b) Check the operation.

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.

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

SST: 09268-31013

09268-41500

90467-13001

95336-08070

SST (Clamp)

(3) Connect SST (adapter and hose) to the injector assembly, and hold the injector assembly and union with SST (clamp).

(4) Set the injector assembly in a graduated cylinder.

CAUTION:

Install a suitable vinyl tube onto the injector assembly to prevent gasoline from spraying.

(5) Operate the fuel pump (See page 2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE FUEL: FUEL SYSTEM: ON-VEHICLE INSPECTION+ ).

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

SST: 09842-30080

Standard Injection Volume:

Tester Connection

Condition

Specified Condition

Positive (+) terminal - Ground terminal

Per 15 seconds

84 to 101 cm3 (5.1 to 6.2 cu in.)

Difference between each injector:

16 cm3 (1.0 cu in.) or less

NOTICE:

Always switch the voltage on and off on the battery side, not the injector side.

If the injection volume is not as specified, replace the injector assembly.

(c) Check for leaks.

(1) Disconnect the tester probes of SST (wire) from the battery and check for fuel leaks from the injector.

Standard Fuel Drop:

1 drop or less every 35 minutes
