Fuel Injector - Inspection

Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 3UR-FE FUEL

FUEL INJECTOR - INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY

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

  • Standard Resistance:
  • Tester ConnectionConditionSpecified Condition
    1 - 220°C (68°F)11.6 to 12.4 Ω

If the result is not as specified, replace the injector assembly.


Inspect the injection volume.

  • CAUTION:
  • This test involves high-pressure fuel and electricity. Take all precautions regarding safe handling of both the fuel and the electricity. Perform this test in a safe area, and avoid any sparks or flames. Do not smoke.

  • 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.

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

Install a vinyl tube to the injector.

*1SST (Wire)
  • 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:
  • 87 to 105 cm3 (5.3 to 6.4 cu in.) per 15 seconds
  • Difference between each injector:
  • 18 cm3 (1.1 cu in.) or less

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


Check for fuel drop.

In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel drop from the injector.

  • Standard fuel drop:
  • 1 drop or less in 12 minutes

If the fuel drop is not as specified, replace the injector assembly.
