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.

(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

(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
).
(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
