1.Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission
Therefore, they should be periodically with new
ones.
2. The new plugs should be checked gap.

6. IGNITION CABLES (Replace)
The ignition cables should. be replaced periodicall y with new
ones. After replacing, make sure that the ignition cables are
routed properly and fully seated.
NOTE
When disconnecting an ignition cable; be sure to ho ld the
cable boot. If the cable is disconnected by pulling on the
cable alone, an open circuit might result.
7. TIMING BELT (Replace)
00100220027
Replace the belt with a new one periodically to ass ure proper
engine performance.
For disassembly and assembly procedures; Refer to GROUP
Timing Belt.
Refer to GROUP
Timing Belt.
Refer to GROUP 11
Timing Belt.
8. DRIVE BELT (For Generator, Water Pump, Power Steering Pump) (Check condition)
Check the tension of the drive belt. Check the driv e belt
for evidence of cuts and cracks, and replace it if defective.

8. If the standard value is exceeded, check the following
items:
l Diagnostic output
l Closed-loop control (When the closed-loop control
is carried out normally, the output signal of the h eated

1.Before inspection, check that the engine-oil, start er
battery are normal. Also, set the to the
condition:
lEngine coolant temperature:
lLights, electric cooling fan and all accessories: O FF
lTransaxle: Neutral (P range on vehicles with
2. Disconnect the spark plug cables.
3. Remove all of the spark plugs.
4.
5.
Disconnect the crankshaft position sensor connector .
NOTE
Doing this will prevent the engine control unit fro m carrying
out ignition and fuel injection.
Cover the spark plug hole with a shop towel etc., a nd
after the engine has been cranked, check that no fo reign
material is adhering to the shop towel.

Caution
1.Keep away from the spark plug hole when crank-
ing.
2. If compression is measured with water, oil, fuel,
etc., that has come from cracks inside the cylinder ,
these materials will become heated and will gush
out from the spark plug hole, which is dangerous.
6.Set compression gauge to one of the spark plug hole s.
7. Crank the engine with the throttle valve fully o pen and
measure the compression pressure.
Standard value (at engine speed of
1,250 (178 psi)
Limit (at engine speed of
min. 935 (133 psi)
8.Measure the compression pressure for all the cylind ers,
and check that the pressure differences of the cylinders
are below the limit.
Limit:. max. 100
(14 psi)
9.If there’ is a cylinder with compression or a compr ession
difference that is outside the limit, pour a small amount
of engine oil through the spark plug hole, and repe at
the operations in steps 7 and
(1) If the compression increases after oil is added , the
cause of the malfunction is a worn or damaged pisto n
ring and/or cylinder inner
(2) If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat,
is leaking from the gasket.
10. Connect the crankshaft position sensor
11. Install the spark plugs and spark plug cables.
12. Use the scan tool to erase the diagnostic
codes,
or disconnect the negative battery cable’ for
than
10 seconds and reconnect it.
NOTE
This will erase the diagnostic trouble code from
the crankshaft position sensor connector being disc on-
nected.

1.Before inspection, set vehicles in the following co ndition:
lEngine coolant temperature:
l Lights, electric cooling fan and all accessories: O FF
lTransaxle: Neutral (P range on vehicles with
2.After turning the ignition switch to OFF, connect t he scan
tool to the data link connector.
3.Start the engine and run it at 2,500 for 2 minutes.
4. Set the CO, HC tester.
5. Check the CO contents and the HC contents at idl e.
Standard value:
CO contents: 0.5% or less
HC contents: 100 ppm or less
6. If the idle speed is outside the standard value, check
the following items: l Diagnostic output
l Closed-loop control (When the closed-loop control
is carried out normally, the output signal of the h eated
oxygen sensor repeats between and
,000 at idle.)

COMPRESSION PRESSURE CHECK
1.Before inspection, check that the engine oil, start er and
battery are normal. Also, set the vehicle to the fo llowing
condition:
lEngine coolant temperature:
lLights, electric cooling fan and all accessories: O FF
