terminals.
Primary coil resistance:
Cold0.54 - 0.84 W
Hot0.68 - 0.98 W
If the resistance is not as specified, replace the ignition coil.
(d) Reconnect the ignition coil connectors.
(e) Reinstall the No.3 timing belt cover.
4. INSPECT CAMSHAFT POSITION SENSORS

GENERAL MAINTENANCE
These are maintenance and inspection items which are considered to be the owner's responsibility.
They can be done by the owner or they can have them done at a service shop.
These items include those which should be checked on a daily basis, those which, in most cases, do not
require (special) tools and those which are considered to be reasonable for the owner to do.
Items and procedures for general maintenance are as follows.
1. GENERAL NOTES

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge. If necessary, adjust.
(b) Check for cuts, damage, uneven or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nuts. If necessary, tighten them.
4. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe clean. If necessary, replace.
5. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or other fluid.
(b) If you smell gasoline fumes or notice any leak, have the cause found and corrected.
6. DOORS AND ENGINE HOOD
(a) Check that all doors and the tailgate operate smoothly, and that all latches lock securely.
(b) Check that the engine hood secondary latch secures the hood from opening when the primary latch
is released.

(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 a new gasket.
(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 the specified
torque.
SST 09631-22020
Torque: 30 N´m (310 kgf´cm, 22 ft´lbf)
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.
(d) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
