CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-860, "
FUEL PRESSURE RELEASE" (with EURO-OBD) or EC-1281,
"FUEL PRESSURE RELEASE" (without EURO-OBD).
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea-
surement.
4. Remove engine cover. Refer to EM-120, "
INTAKE MANIFOLD" .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-132, "
IGNITION COIL" and EM-133,
"SPARK PLUG (PLATINUM-TIPPED TYPE)" .
6. Connect an engine tachometer (not required in use of CONSULT-II).
7. Install a compression tester (B) with an adapter (commercial
service tool) (A) 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/cm
2
, psi) /rpm
CAUTION:
Always use fully a changed battery to obtain the specified engine speed.
