CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure by “Without CONSULT-II”. Refer to EC-48, "
FUEL PRESSURE RELEASE" (WITH
EURO-OBD) or EC-510, "
FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).

Leave fuel pump fuse disconnecting to avoid fuel injection during measurement.
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-29, "
IGNITION COIL" and EM-30,
"SPARK PLUG" .
4. Connect engine tachometer (not required in use of CONSULT-II).
5. Install compression tester with adapter onto spark plug hole.

Use compression gauge 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.
6. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (bar, kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain specified engine speed.

If the engine speed is out of 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 cylinders have 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
piston rings and replace if necessary.
