INSPECTION PROCEDURE 1. INSPECT FUEL INJECTOR ASSEMBLY
| (a) 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) 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.
| (1) Remove the fuel pipe clamp. | |
(2) Disconnect the No. 1 fuel pipe sub-assembly (for Quick Type B) (See page
 ).
| (3) Connect SST to the fuel pipe (the vehicle side). SST: 09268-31014
09268-41500 09268-41700 95336-08070 | |
| (4) Install the O-ring to the fuel injector assembly. | |
(5) Install SST and the tube to the fuel injector assembly. SST: 09268-31014
09268-41300 09268-41500 09268-41600 09268-41700
| (6) Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).
SST: 09268-31014 09268-41800
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.
NOTICE:
- Make sure that SST (EFI inspection wire I) is securely connected.
- Always turn the voltage on and off on the battery side, not the fuel pump side.
(9) Operate the fuel pump (turn the ignition switch to ON).
| (10)
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:
83 to 99 cm3 (5.0 to 6.0 cu in.) per 15 seconds Difference between each injector:
16 cm3 (1.0 cu in.) or less If the injection volume is not as specified, replace the fuel injector assembly. |
|
(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 12 minutes | | |
