Inspection [06/2017 - ]: Procedure
- INSPECT 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.
*a Component without harness connected
(Fuel Injector Assembly)
- Measure the resistance according to the value(s) in the table below.
- Check the operation.WARNING:
Perform the inspection in a well-ventilated area.
Do not perform the inspection near an open flame.
- Disengage the 2 claws to remove the No. 2 fuel pipe clamp.
- Remove the No. 1 fuel pipe clamp from the fuel tube connector.
- Disconnect the fuel tube sub-assembly.
Refer to PRECAUTION [06/2017 - 09/2019] , or refer to PRECAUTION [09/2019 - ]
- Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).
*a SST (Hose) *b SST (Hose Band) *c SST (Fuel Tube Connector) *d 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.
- SST: 09268-31015
- Apply a light coat of gasoline to a new O-ring, and then install the O-ring to the fuel injector assembly.
- Connect SST (adapter) and SST (hose) to the fuel injector assembly, and hold the fuel injector assembly and union with SST (clamp).
*1 O-ring *a SST (Adapter) *b SST (Hose Band) *c SST (Clamp) *d SST (Hose) *e Vinyl Tube - SST: 09268-31015
- 09268-41600
- 09268-41300
- 09268-41700
- 95336-08070
- SST: 09268-31015
- Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.
*a Lock *b SST (Tie Band) - 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.
HINT:
When removing SST (tie band), disengage the lock.
- SST: 09268-31015
- Check that SST (clamp) and SST (adapter) cannot be easily separated.
- Install a vinyl tube to the fuel injector assembly.WARNING:
Install a suitable vinyl tube to the fuel injector assembly to prevent fuel from spraying.
- Set the fuel injector assembly into a graduated cylinder.
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).NOTE:
Do not start the engine.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.
Powertrain > Engine > Active Test
Tester Display Activate the Circuit Relay - 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.
*a SST (EFI Inspection Wire I) - 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 Fuel Injector Assembly
14 cc (0.9 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 injection volume is not as specified, replace the fuel injector assembly.
- Disengage the 2 claws to remove the No. 2 fuel pipe clamp.
- Check for leaks.
- Disconnect SST (EFI inspection wire I) 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.
- Connect the fuel tube sub-assembly.
Refer to PRECAUTION [06/2017 - 09/2019] , or refer to PRECAUTION [09/2019 - ]
- Install the No. 1 fuel pipe clamp to the fuel tube connector.
- Engage the 2 claws to install the No. 2 fuel pipe clamp.
- Check for fuel leaks.
Refer to PROCEDURE - Step 1
- Disconnect SST (EFI inspection wire I) from the battery and check for fuel leaks from the fuel injector assembly.
- Check the resistance.
