CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-78, "
Fuel Pressure Check".
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea-
surement.
4. Remove engine cover. Refer to EM-18, "
Component".
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-30
.
6. Connect an engine tachometer (not required in use of CONSULT-III).
7. Install a suitable compression tester with an adapter onto spark
plug hole.
• Use the adapter whose picking up end inserted to spark plug
hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
Compression pressure:
Unit: kPa (bar, kg/cm2 psi) /rpm
CAUTION:
Always use a fully charged battery to obtain the specified engine speed.

• If the engine speed is out of the specified range, check battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
• If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
9. After inspection is completed, install removed parts.
10. Start the engine, and confirm that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-81
.

ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001703098
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.

safe area.
CAUTION:
• Use gasoline required by the regulations for octane number. Refer to GI-4, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
• Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines. Refer to EC-78, "
