Compression Check: Testing and Inspection

Check compression pressure on all four cylinders as follows:
1. Warm up engine.
2. Stop engine after warming up.
3. Remove all spark plugs and disconnect fuel injector wire harness at coupler.





4. Disconnect ignition coil wire harness at coupler.

WARNING: Failure in disconnecting ignition coil coupler can cause spark to occur in engine room possibly resulting in a dangerous explosion.





5. Install special tool (Compression gauge) into spark plug hole.

Special Tool, or equivalent (A): 09915-64510





6. Disengage clutch (to lighten starting load on engine) for M/T model, and depress accelerator pedal all the way to make throttle valve full-open.
7. Crank engine with fully charged battery, and read the highest pressure on compression gauge.

NOTE: For measuring compression pressure, crank engine at least 250 r/min. by using fully charged battery.

Compression pressure:
Standard: 1400 kPa (199.0 psi)
Limit: 1100 kPa (156.4 psi)
Max. difference between any two cylinders: 100 kPa (14.2 psi)

8. Carry out steps 5 through 7 on each cylinder to obtain four readings.
9. After checking, connect coupler of ignition coil and install spark plugs.
