9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Remove the intake air surge tank (see page 11-13).
(c) Disconnect the injector connectors.
(d) Remove the ignition coils.
(e) Remove the spark plugs.
(f) Inspect the cylinder compression pressure.
(1) Insert a compression gauge into the spark plug
hole.
SST 09992-00500
(2) Fully open the throttle.
(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1.5 MPa (15.3 kgf/cm
2, 218 psi)
Minimum pressure:
1.0 MPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi)
NOTICE:

Always use a fully-charged battery to obtain engine
speed of 250 rpm or more.

Check the other cylinder's compression pressure in
the same way.

This measurement must be done as quickly as pos-
sible.
(4) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
spark plug hole, then inspect again.
HINT:

If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.

If pressure stays low, the valve may be sticking or seated
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
HINT:
The ECM properly controls the CO/HC concentration in the emission gas.
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert the CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check the CO/HC concentration at idle and/or at 2,500 rpm.
HINT:
When doing the 2 mode (with the engine is at idle and at 2,500 rpm) tests, these measuring order are pre-
scribed by the applicable local regulations.
If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.
(1) Check the heated oxygen sensor operation (see page 05-126).
