CIRCUIT DESCRIPTION
Misfire: The ECM uses the crankshaft position sensor and camshaft position sensor to monitor changes in
the crankshaft rotation for each cylinder.
The ECM counts the number of times the engine speed change rate indicates that misfire has occurred.
When the misfire rate equals or exceeds the count indicating that the engine condition has deteriorated, the
MIL lights up.
If the misfire rate is high enough and the driving conditions will cause catalyst overheating, the MIL blinks
when misfiring occurs.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT IGNITION COIL CONNECTORS
3. REMOVE SPARK PLUGS (See page IG±1)
4. INSPECT CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,226 kPa (12.5 kgf/cm
2, 178 psi) or more
Minimum pressure: 981 kPa (10.0 kgf/cm
2, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) If the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.

If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.

If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG±1)
6. RECONNECT IGNITION COIL CONNECTORS

INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE CYLINDER HEAD COVER
(a) Disconnect the 4 high±tension cords from the clamps on
the cylinder head cover.
(b) Disconnect the 4 high±tension cords from the spark
plugs.
(c) Disconnect the PCV hose from the intake manifold.
(d) Disconnect the PCV hose from the cylinder head cover.
(e) Disconnect the engine wire clamp from the mounting bolt
of the No.2 timing belt cover.
(f) Remove the cylinder head cover. (See page EM±33)
2. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are loose
and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360°) and align the
mark as above.
3. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record the out±of±specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust0.28 ± 0.38 mm (0.011 ± 0.015 in.)
(b) Turn the crankshaft one revolution (360°) and align the
mark as above.

When re±using timing belt:
Affix the matching marks on the timing belt and the camshaft
timing pulley, and the timing belt and the No. 1 timing belt cover.
(a) Loosen the mounting bolt of the No.1 idler pulley, and shift
the pulley toward the left as far as it will go, and temporari-
ly tighten it.
(b) Remove the timing belt from the camshaft timing pulley.
