FUEL INJECTOR INSPECTION

PROCEDURE

INSPECT FUEL INJECTOR ASSEMBLY

*a	Component without harness connected (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 fuel injector assembly.

Check the operation.

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.

*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 )

Note

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 fuel injector assembly.

*1	O-ring
*a	SST (Hose)
*b	SST (Hose Band)
*c	SST (Adapter)
*d	SST (Clamp)
*e	Vinyl Tube

Connect SST (adapter) and SST (hose) to the fuel injector assembly, and hold the fuel injector assembly and union with SST (clamp).

SST: 09268-31015 ( 09268-41110, 09268-41300, 09268-41700, 95336-08070 )

Install a vinyl tube to the fuel injector assembly.

CAUTION:

Install a suitable vinyl tube to the fuel injector assembly to prevent fuel from spraying.

*a	SST (Tie Band)
*b	SST (Adapter)
*c	SST (Clamp)
*d	Lock

Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

SST: 09268-31015 ( 09268-41800 )

Note

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 (tie band).

Tech Tips

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

Check that SST (clamp) and SST (adapter) cannot be easily separated.
Set the fuel injector assembly in a graduated cylinder.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.

Note

Do not start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.

Powertrain > Engine and ECT > Active Test

*a	SST (EFI Inspection Wire H)
*b	Connect

Connect SST (EFI inspection wire H) to the fuel injector assembly and battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each fuel injector assembly 2 or 3 times.

SST: 09842-30080

Standard Injection Volume

Battery Connection	Condition	Specified Condition
Positive (+) battery terminal - Negative (-) battery terminal	Per 15 seconds	87 to 105 cc (5.3 to 6.4 cu. in.)

Difference between Each Fuel Injector Assembly
18 cc (1.1 cu. in.) or less

Note

Make sure that SST (EFI inspection wire H) is securely connected.
Always switch the voltage on and off at the battery side, not the fuel injector assembly side.

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

Turn the ignition switch off.
Disconnect the GTS from the DLC3.

Check for leaks.
1. Disconnect SST (EFI inspection wire H) from the battery and check for fuel leaks from the fuel injector assembly.
  
  Standard Fuel Drop
  
  1 drop or less per 20 minutes
  
  If the result is not as specified, replace the fuel injector assembly.
2. Check for fuel leaks.
