PROCEDURE
INSPECT PORT FUEL INJECTOR ASSEMBLY
Check the resistance.
*a | Component without harness connected (Port Fuel Injector Assembly) |
Measure the resistance according to the value(s) in the table below.
Standard Resistance | ||||||
---|---|---|---|---|---|---|
|
If the result is not as specified, replace the port 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 | w/ Canister Pump Module |
*B | w/o Canister Pump Module |
Remove the No. 2 fuel pipe clamp.
Note
Do not reuse the No. 2 fuel pipe clamp.
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).
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 SST (fuel tube connector) and the fuel pipe (vehicle side).
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).
*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.
Tech Tips
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.
Operate the fuel pump.
*a | SST (EFI Inspection Wire H) |
Connect SST (EFI inspection wire H) 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.
Standard Injection Volume | ||||||
---|---|---|---|---|---|---|
|
Difference between Each Port Fuel Injector Assembly |
---|
15 cc (0.9 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 port fuel injector assembly side.
If the injection volume is not as specified, replace the port fuel injector assembly.
Check for leaks.
Disconnect SST (EFI inspection wire H) from the battery and check for fuel leaks from the port fuel injector assembly.
Standard Fuel Drop |
---|
1 drop or less per 14 minutes |
If the result is not as specified, replace the port fuel injector assembly.
Connect the fuel tube sub-assembly.
Install a new No. 2 fuel pipe clamp.
Check for fuel leaks.
