TEXT IN ILLUSTRATION

*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 injector assembly.

Check the operation.

WARNING:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.

Connect SST (fuel tube connector) to SST (hose), and then connect them to the fuel pipe (vehicle side).

*5	Vinyl Tube
*6	SST (Clamp)

Connect SST (adapter and hose) to the injector assembly, and hold the injector assembly and union with SST (clamp).
Set the injector assembly in a graduated cylinder.
WARNING:
Install a suitable vinyl tube onto the injector assembly to prevent gasoline from spraying.
Operate the fuel pump (Refer to PROCEDURE - Step 1 ).

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

Standard Injection Volume

Tester Connection	Condition	Specified Condition
Positive (+) terminal - Ground terminal	Per 15 seconds	84 to 101 cm³ (5.1 to 6.2 cu in.)

Difference between each injector

16 cm³ (1.0 cu in.) or less

NOTE:

Always switch the voltage on and off on the battery side, not the injector side.

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

Check for leaks.

Disconnect the tester probes of SST (wire) from the battery and check for fuel leaks from the injector.
Standard Fuel Drop

1 drop or less every 35 minutes
