Toyota Sienna Service Manual: Inspection

1. INSPECT FUEL INJECTOR ASSEMBLYV

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.

 INSPECT FUEL INJECTOR ASSEMBLYV

(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).

INSPECT FUEL INJECTOR ASSEMBLYV

(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.

INSPECT FUEL INJECTOR ASSEMBLYV

(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
