Fuel Injector (for Port Injection)

1UR-FSE FUEL: FUEL INJECTOR (for Port Injection): INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) Check the resistance of the injector.





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

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 all precautions regarding safe handling of both the fuel and electricity components. Perform this test in a safe area, and avoid any sparks or flames. Do not smoke.

(1) Remove the fuel pipe clamp.





(2) Disconnect the fuel tube.





NOTICE:
Do not use any tools in this procedure.

HINT
If the connector and tube are stick, pinch the connector and push and pull the tube to disconnect them.

(3) Connect SST to the vehicle side fuel pipe.





SST : 09268-31014

09268-41500

09268-41700

95336-08070

(4) Install a new the O-ring to the fuel injector.

(5) Install SST and the tube to the fuel injector.

09268-41300

09268-41600

NOTICE:
* Make sure that SST (adapter) and SST (clamp) are not loose and do not rattle.
* Install a suitable vinyl tube to the injector to contain any gasoline spray.

(6) Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).

NOTICE:
* As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.
* Before using SST (tie band), make sure that there is no deterioration, damage or cracks. If there are any abnormalities, replace SST.

HINT
When removing SST (tie band), disengage the lock.

(7) Check that SST (clamp) and SST (adapter) cannot be easily separated.

(8) Put the injector into a graduated cylinder.





CAUTION:
Install a strong rubber tube onto the injector to prevent gasoline from splashing.

Operate the fuel pump (turn the engine switch on (IG)).

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 : 09842-30090

Standard injection volume:

84 to 102 cc (5.1 to 6.2 cu. in.) per 15 seconds

Difference between each injector: 18 cc (1.1 cu. in.) or less

NOTICE:
* Make sure that SST (EFI inspection wire H) is securely connected.
* Always do the switching at the battery side.

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.





Standard fuel drop:

1 drop or less in 20 minutes
