NOTE:
. Replace the timing belt at 105,000 miles (168.000 km)
according to the maintenance schedule (normal con-
ditions/severe conditions).
lf the vehicle is regularly driven in one or more of the
followlng conditions, replace the timing belt at 60.000
miles (U.S.A.) 100,000 km {Canada).
.In very high temperatures (over 110'F.43'C)
. In very low temperatures (under -20'F, -29"C)'
! Turn the crankshaft pulley so the No. 1 piston is at
top dead center (TDC) before removing the belt (see
page 6'21).
. Inspect the water pump before installing the timing
belt {see Page 10-14).

correct positions on the engine.
CAUTION:
. Use tender covels to avoid damaging painted sul-
faces.
o To avoid damage, unplug the wiling connectors
carefully while holding the connector portion to
avoid damage.
. To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F
{38"C} before loossning the tetaining bolts.
NOTE:
o Mark all wiring and hoses to avoid misconnectlon
Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.
. Inspect the timing belt before removing the cylinder

Removal
NOTE:
. Replace the timing belt at 105,000 mites (168,000 km)according to the maintenance schedule (normal con-ditions/severe conditions).
lf the vehicle is regularly driven in one or more of thefollowing conditions, replace the timing belt at 60,OOOmiles (U.S.A.) 100,000 km {Canada).. In very high temperatures (over 110"F, 43"C).. In very low temperatures (under -20.F, 29.C).. Turn the crankshaft pulley so the No. 1 piston is attop dead center (TDC) before removing the belt (seepage 6-57).
. Inspect the water pump before installing the timingbelt {see page 10-14).

Removal
Engine removal is not required for this procedure.
!@@ Make sure jacks and safety stands are placed
properly and hoist brackels are attached to correst posi-
tion on the engine,
CAUTION:
o Use fender covers to avoid damaging painted sur-
faces.
To avoid damage, unplug the wiling connectors
carelully while holding the connector portion.
To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F {38'Cl
before loosening the retaining bolt.
NOTE:
. Unspecified items are common.
. Mark all wiring and hoses to avoid misconnection.
AIso, be sure that they do not contact other wiring or
hoses or interfere with other parts.
o Inspect the timing belt before removing the cylinder
n eao.
. Turn the crankshaft pulley so that the No. 1 piston is
at top dead center (see page 6-64).
1. Disconnect the negative terminal from the battery.
Drain the engine coolant {see page 10-7).
. Remove the radiator cap to speed draining.
Remove the strut brace (see page 5-2).
Remove the intake air duct and air cleaner housing
(see page 5-3).
Remove the adjusting bolt and mounting bolt, then
remove the power steering (P/S) pump belt and pump
(see page 5 5).

PGM-FI Sy3lem
The PGM-Fl system on this model is a sequential multipon fuel injection system.
Fuel iniector Timing and Duration
The ECM/PCM contains memories for the basic discharge durations at various engine speeds and manifold air flow rates.
The basic discharge duration, after being read out from the memory. is further modified by signals sent from various sen-
sors to obtain the final discharge duration.
ldle Air Control
ldle Air Control Valve llAC Valve)
When the engine is cold. the A,/C compressor is on, the transmission is in gear, the brake pedal is depressed, the P/S load
is high, or the alternator is charging, the ECM/PCM controls current to the IAC Valve to maintain the correct idle speed.
lgnition Timing Control
. The ECM/PCM contains memories for basic ignition timing at various engine speeds and manifold air flow rates.
lgnition timing is also adjusted for engine coolant temperature.
. Aknockcontrol system was adopted which sets the ideal ignition timing for the octane rating ofthegasoline used.*3
Othgr Control Funqtions
1. Starting Control
When the engine is started, the ECM/PCM provides a rich mixture by increasing fuel injector duration.
2. Fuel Pump Control
. When the ignition switch is initially turned on, the ECM/PCM supplies ground to the PGM-Fl main relay that sup-plies current to the fuel pump for two seconds to pressurize the fuel system.. When the engine is running, the ECI\4PCM supplies ground to the PGM-FI majn relay that supplies current to the fuel
oumo.
. When the engine is not running and the ignition is on, the ECM/PCM cuts ground to the PGM-FI main relay which
cuts current to the fuel pump.
