(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure
1,300 kPa (13.3 kgf cm
2, 189 psi)
Minimum pressure: 1,000 kPa (10.2 kgf cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf cm
2, 14 psi)
NOTICE:
Always use a fully charged battery to obtain engine
speed of 250 rpm or more.
Check other cylinder's compression pressure in the
same way.
This measurement must be done in as short a time as
possible.
(4) If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into the cyl-
inder through the spark plug hole and repeat steps
(1) through (3) for the cylinders that have low com-
pression.
HINT:
If adding oil helps increase the compression, the piston
rings and/or cylinder bore may be worn or damaged.
If pressure stays low, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tail\
pipe during idling.
(d) Check CO/HC concentration at idle.
Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
If the CO/HC concentration does not conform to specifications, perform tro\
ubleshooting in the order given
below.
Check heated oxygen sensor operation.
See the table below for possible causes, and then inspect and repair the applicable causes if
necessary.
