Replace the timing belt at 105,000 miles (168,000 km)
according to the maintenance schedule {normal condi-
tions/severe conditions). lf the vehicle is regularly driven
in either of the following conditions, replace the timing
belt at 60,000 miles (U.S.A.l 100.000 km (Canada).
- ln very high temperatures (over 110'F, 43"C).- In very low temperatures (under -20"F. -29"C).
Turn the crankshaft pu\ley so the No. 1 piston is at
top dead center (TDC).
Remove the guard bar and splash shield (see page

Valve Guides
Valve Movement
1. Measure the guide-to-stem clearance with a dial
indicator while rocking the stem in the direction of
normal thrust (wobble method),
lntake Valve Stem-to-Guide Clearance:
Standard (Newl: 0.04 - 0.10 mm
(0.002 - 0.004 in)
Service Limit 0.16 mm (0.006 in)
Exhaust Valve Stem-to-Guide Clearance:
Standard {Newl: 0.10 - 0.16 mm
(0.004 - 0.006 inl
Service Limit: 0,22 mm (0.009 inl
lf the measurement exceeds the service limit,
recheck using a new valve.
lf the measurement is now within the service limit,
reassemble using a new valve.
lf the measurement still exceeds the limit, subtract the
O.D. of the valve stem, measured with a micrometer,
from the l.D. of the valve guide, measured with an
inside micrometer or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide
The difference between the largest guide measure-
ment and the smallest stem measurement should
not exceed the service limit.
lntake Valve Stem-to-Guide Clearance:
Standard (New): 0.02 - 0.05 mm
{0.001 - 0.002 in)
Service Limit: 0.08 mm (0.003 in)
Exhaust Valve Stem-to-Guide Clearance:
Standard (New): 0.05 - 0.08 mm

Replacement
1. As illustrated below, use a commercially available
air-impact valve guide driver attachment modified
to fit the diameter of the valve guides. In most
cases, the same procedure can be done using the
sDecial tool and a conventional hammer.

Use a hot plate or oven to evenly heat the cylinder
head to 300"F (150"C). Monitor the temperature with
a cooking thermometer. Do not get the head hofter
than 300'F (150"C); excessive heat may loosen the

Fuel Cut-off Control
. During deceleration with the throttle valve closed, current to the fuel injectors iscutoffto improvefuel economyat
speeds over 970 rpm ('97 - 98 models), 920 rpm ('99 - 00 modelsl.
. Fuel cut-off action also takes place when engine speed exceeds 6,500 rpm ('97 - 98 models), 6900 rpm ('99 - 00
models), regardless of the position of the throttle valve, to protect the engine from over-rewing.
With Ay'T model. the PCM cuts the fuel at engine speeds over 5,000 rpm when the vehicle is not moving.*'
4,./C Comoressor Clutch Relav
When the ECM/PCM receives a demand for cooling from the air conditioning system, it delays the compressor from
being energized, and enriches the mixture to assure a smooth transition to the Ay'C mode.
Evaporative Emission (EVAP) Purge Control Solenoid Valve
When the engine coolant temperature is above 154"F (68'C), the ECM/PCM controls the EVAP purge control solenoid
valve which controls vacuum to the EVAP purge control canister,
Alternator Control
The system controls the voltage generated at the alternator in accordance with the electrical load and driving mode.
which reduces the engine load to improve the fuel economy.
PCM Fail-saf e/Back-up Functions
1. Fail-safe Function
When an abnormality occurs in a signal from a sensor, the ECM/PCM ignores that signal and assumes a pre-pre
grammed value for that sensor that allows the engine to continue to run.
2. Back-up Function
When an abnormality occurs in the ECM/PCM itself, the fuel injectors are controlled by a back-up circuit independent
of the system in order to permit minimal driving.
3. Self-diagnosis Function IMalfunction Indicator Lamp (MlL)l
When an abnormality occurs in a signal from a sensor, the ECM/PCM supplies ground for the MIL and stores the DTC
in erasable memory. When the ignition is initially turned on {ll), the ECM/PCM supplies ground for the MIL for two
seconds to check the MIL bulb condition.
4. Two Trio Detection Method
To prevent false indications, the Two Trip Detection Method is used for the HO2S*1, fuel metering-related. idle control
system, ECT sensor and EVAP control system self-diagnostic functions. When an abnormality occurs, the ECM/PCM
stores it in its memory. When the same abnormality recurs after the ignition switch is turned OFF and ON (ll) again,
the ECM/PCM informs the driver by lighting the MlL. However, to ease troubleshooting, this function is cancelled
when you jump the service check connector, The MIL will then blink immediately when an abnormality occurs.
5. Two (or Three) Driving Cycle Detection Method {'97 model)
A "Driving Cycle" consists of starting the engine, beginning closed loop operation, and stopping the engine. lf misfir-
ing that increases emissions or EVAP control system malfunction is detected during two consecutive driving cycles.
or TWC deterioration is detected during three consecutive driving cycles, the ECM/PCM turns the MIL on. However, to
ease troubleshooting, this function is cancelled when you jump the service check connector. The MIL will then blink
immediately when an abnormality occurs.
