7GR-FKS FUEL FUEL INJECTOR(for Port Injection) INSPECTION
PROCEDURE
23250F
1.INSPECT PORT FUEL INJECTOR ASSEMBLY
Check the resistance.
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 port fuel 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.
Remove the No. 2 fuel pipe clamp.
Disconnect the fuel tube sub-assembly (for Port Injection).
| *a | SST (Hose) |
| *b | SST (Hose Band) |
| *c | SST (Fuel Tube Connector) |
| *d | Fuel Pipe (Vehicle Side) |
Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).
- SST
- 09268-31015 (09268-41500, 09268-41700, 95336-08070)
- NOTICE:
-
Make sure the SST (fuel tube connector) O-rings are not damaged and are free of foreign matter as they are used to seal the connections between the fuel tube connector and fuel pipe.
Apply a light coat of gasoline to a new O-ring, and then install the O-ring to the port fuel injector assembly.
| *1 | O-ring |
| *a | SST (Adapter) |
| *b | SST (Hose Band) |
| *c | SST (Clamp) |
| *d | SST (Hose) |
| *e | Vinyl Tube |
Connect SST (adapter) and SST (hose) to the port fuel injector assembly, and hold the port fuel injector assembly and union with SST (clamp).
- SST
- 09268-31015 (09268-41600, 09268-41300, 09268-41700, 95336-08070)
| *a | Lock |
| *b | SST (Tie Band) |
Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.
- SST
- 09268-31015 (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 wear, 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 port fuel injector assembly.
- CAUTION:
-
Install a suitable vinyl tube to the port fuel injector assembly to prevent fuel from spraying.
Set the port fuel injector assembly into a graduated cylinder.
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
- NOTICE:
-
Do not start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.
- Powertrain > Engine > Active Test
-
Tester Display Activate the Circuit Relay - 50004 372 40
| *a | SST (EFI Inspection Wire I) |
Connect SST (EFI inspection wire I) to the port fuel injector assembly and battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each port fuel injector assembly 2 or 3 times.
- SST
- 09842-30090
- Standard Injection Volume:
Tester Connection Condition Specified Condition Positive (+) battery terminal - Negative (-) battery terminal Per 15 seconds 67 to 81 cc (4.1 to 4.9 cu. in.)
- Difference between Each Port Fuel Injector Assembly:
14 cc (0.9 cu. in.) or less
- NOTICE:
- ·
Make sure that SST (EFI inspection wire I) is securely connected.
·Always switch the voltage on and off at the battery side, not the port fuel injector assembly side.
If the injection volume is not as specified, replace the port fuel injector assembly.
Turn the engine switch off.
Disconnect the GTS from the DLC3.
Check for leaks.
Disconnect SST (EFI inspection wire I) from the battery and check for fuel leaks from the port fuel injector assembly.
- Standard Fuel Drop:
1 drop or less per 20 minutes
If the result is not as specified, replace the port fuel injector assembly.
Install the No. 1 fuel pipe clamp to the fuel tube connector.
