FUEL INJECTOR INSPECTION

PROCEDURE

INSPECT FUEL INJECTOR ASSEMBLY

*a	Component without harness connected (Fuel Injector Assembly)

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.

Inspect the fuel injector assembly injection.

CAUTION:

Keep the fuel injector assembly away from sparks during the test.

Disconnect the fuel tube sub-assembly.

*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).

Apply a light coat of gasoline to a new O-ring. Then install the O-ring onto 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 them with SST (clamp).

*a	Lock
*b	SST (Tie Band)

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

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.

Tip:

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

Check that SST (clamp) and SST (adapter) cannot be easily separated.
Install a vinyl tube onto the fuel injector assembly.

CAUTION:
Install a suitable vinyl tube onto the fuel injector assembly to prevent fuel from spraying.
Set the fuel injector assembly in a graduated cylinder.
Connect the cable to the negative (-) battery terminal.
Connect the GTS to the DLC3.
Turn the ignition switch on (IG).

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 I)

Connect SST (EFI inspection wire I) 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.

Standard Injection Volume


Battery Connection	Condition	Specified Condition
Positive (+) battery terminal - Negative (-) battery terminal	Per 15 seconds	32 to 38 cc (2.0 to 2.3 cu.in.)

Difference between Each Fuel Injector Assembly

6 cc (0.3 cu. in.) or less

Note:

Make sure that SST (EFI inspection wire I) 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.

Check for fuel drop.
1. In the condition above, disconnect SST (EFI inspection wire I) from the battery and check for fuel drop from the fuel injector assembly.
  
  Standard Fuel Drop
  
  1 drop or less per 205 minutes
  
  If the result is not as specified, replace the fuel injector assembly.
2. Turn the ignition switch off.
3. Disconnect the GTS from the DLC3.
4. Disconnect the cable from the negative (-) battery terminal.
  
  Note:
  When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
