COMPRESSION CHECK
Check compression pressure on all 6 cylinders as follows:
1) Warm up engine.
2) Stop engine after warming up.
3) Remove ignition coil covers and disconnect ignition coil har-
ness couplers.
4) Remove all ignition coils and spark plugs.
5) Remove surge tank cover.
6) Disconnect fuel injector wire harness at connector.
7) Install special tool (Compression gauge) into spark plug hole.
Special Tool
(A): 09915-64510
(B): 09915-64530
(C): 09915-67010
8) Disengage clutch (to lighten starting load on engine) for M / T
vehicle, and depress accelerator pedal all the way to make
throttle fully open.
9) 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 (rpm) by using fully charged battery.
Compression pressure
Standard: 14.0 – 16.0 kg / cm
2
(199.0 – 227.5 psi, 1400 – 1600 kPa)
Limit:
13.0 kg / cm
2
(185.0 psi, 1300 kPa)
Max. difference between any two cylinders:
1.0
kg / cm
2
(14.2 psi, 100 kPa)
10) Carry out steps 7), 8) and 9) on each cylinder to obtain 6 read-
ings.
