Toyota Sienna Service Manual: Inspection
1. INSPECT FUEL INJECTOR ASSEMBLYV
(A) inspect the injector resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
Standard resistance
If the resistance is not as specified, replace the injector.
(b) Inspect the injection volume.
| CAUTION:
This test involves high-pressure fuel and
electricity. Take every precaution regarding the
safe handling of both fuel and electricity.
Perform this test in a safe area, and avoid any sparks or flames. Do not smoke. |
(1) Install the fuel tube connector to SST (hose), then connect the tube connector to the fuel pipe (vehicle side).
SST 09268-31011 (09268-41500, 90467- 13001, 95336-08070)
(2) Install the O-ring to the fuel injector subassembly.
(3) Connect SST (adaptor and hose) to the injector, and hold the injector and union with SST (clamp).
SST 09268-31011 (90467-13001, 95336- 08070), 09268-41140, 09268-41400
(4) Put the injector into the graduated cylinder.
| CAUTION: Install a suitable vinyl tube onto the injector to contain gasoline spray. |
(5) Operate the fuel pump (See page FU-7).
(6) Connect SST (wire) to the injector 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
Volume: 84 to 100 cm3 (5.1 to 6.0 cu in.) in 15 seconds
Difference between each injector: 16 cm3 (0.98 cu in.) or less
If the injection volume is not as specified, replace the injector.
(c) Check for leakage.
(1) In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel leakage from the injector.
Fuel drop: 1 drop or less in 16 minutes

Rear Speed Sensor RH Circuit
DESCRIPTION
Refer to DTCs C0200/31, C0205/32, C1235/35, and C1236/36 (See page BC-17).
DTCs C1273/73 to C1278/78 can be deleted when the speed sensor sends a vehicle
speed signal or the
Test Mode ends. DTCs C1273/73 to C1278/78 are output only in the Test Mode.

Meter Illumination is Always Dark
DESCRIPTION
Confirm that the vehicle is equipped with the optitron meter, then
check this circuit.
The combination meter assembly receives a auto dimmer signal from the
body ECU by the multiplex
communication line.
