Off Vehicle Inspection

1. INSPECT INJECTOR INJECTION.

CAUTION: Keep injector clear of sparks during the test.

- Remove the 2 bolts and fuel hose clamp.

- Disconnect the fuel inlet hose from the fuel tube.
- Connect SST 09268-41045 (hose) to the fuel inlet tube with SST 90405-52010 (union).
- Tighten the flare nut on the fuel tube.

Torque: 30 Nm (22 ft lb)

HINT: Use SST 09631-22020.

- Install a new 0-ring to the fuel inlet of the pressure regulator.
- Connect SST 09268-41045 (hose) to the fuel inlet of the pressure regulator with SST 09268-41090 (union) and the 2 bolts.
- Connect the fuel return hose to the fuel outlet of the pressure regulator with SST (union), 2 new gaskets and union bolt.

- Install the grommet and a new 0-ring to the injector.
- Connect SST (hose) to the injector with SST (union), and hold the injector and union with SST 09268-41045 (clamp).
- Put the injector into the graduated cylinder.

HINT: Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out.

- Using SST 09843-18020, connect terminals +B and FP of the DLC1.
- Reconnect the negative (-) terminal cable to the battery.
- Turn the ignition switch ON.

NOTICE: Do not start the engine.

- Connect SST 09842-30070 (wire) to the injector and battery for 15 seconds, and measure the injection volume with a graduated cylinder.
- Test each injector 2 or 3 times.

Volume: 70 - 88 Cm3 (4.3 - 5.4 Cu in) per 15 sec.
Difference between each injector: 9 cm3 (0.5 cu in) or less

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

2. INSPECT LEAKAGE.
- In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leakage from the injector.

Fuel drop: 1 drop or less per minute

- Disconnect the negative (-) terminal cable from the battery.
- Remove SST.

- Reconnect the fuel inlet hose to the fuel tube.

Torque: 30 Nm (22 ft lb)

HINT: Use a torque wrench with a fulcrum length of
30cm (11.81 in).

- Install the fuel hose clamp with the 2 bolts.
