Compression Check: Testing and Inspection

Check compression pressure on all four cylinders as follows:
1. Warm up engine.
2. Stop engine after warming up.

NOTE: After warming up engine, place transmission gear shift lever in "Neutral" (shift selector lever to "P" range for A/T model), and set parking brake and block drive wheels.





3. Disconnect couplers from both ignition coil assemblies.

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





4. Remove all spark plugs and disconnect fuel injector wire harness at couplers.
5. Install special tool (Compression gauge) into spark plug hole.

Special Tool
(A): 09915-64510-001
(B): 09915-64510-002
(C): 09915-64530
(D): 09915-67010





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.
8. Carry out steps 5)through 7)on each cylinder to obtain four readings.
9. After checking, connect couplers to ignition coil assembly and fuel injectors securely and install spark plugs.
