DIAGNOSTIC TROUBLE CODE CHART
HINT:
Parameters listed in the chart may not be exactly the same as your reading due to the type of instrument
or other factors.
If a malfunction code is displayed during the DTC check in check mode, check the circuit for that code listed
in the table below, for details of each code, turn to the page referred to under the ”See page” for the respec-
tive ”DTC No.” in the DTC chart.

(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe the following procedures:
(1) Union Bolt Type:
Always use 2 new gaskets.
(2) Union Bolt Type:
Tighten the union bolt by hand.
(3) Union Bolt Type:
Tighten the union bolt to the specified torque.
Torque: 29 N·m (300 kgf·cm, 22 ft·lbf)
(4) Flare Nut Type:
Apply a light coat of engine oil to the flare nut, and
tighten the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to specified torque.
SST 09631−22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque: 34 N·m (350 kgf·cm, 25 ft·lbf)
28 N·m (285 kgf·cm, 21 ft·lbf) for SST
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(c) Observe the following precautions when removing and
installing the injectors.
(1) Never reuse the O−ring.
(2) When placing a new O−ring on the injector, take
care not to damage it in any way.
(3) Coat a new O−ring with spindle oil or gasoline be-
fore installing−never use engine, gear or brake oil.
(4) Install the injector to the delivery pipe and intake
manifold as shown in the illustration.
