(5) Disconnect terminals 13 (TC) and 4 (CG) of DLC3.
(6) Inspect ignition timing at idle.
Ignition timing: 5 to 15 BTDC
(7) Confirm that ignition timing to go advanced angle
side when the engine rpm is increased.
(8) Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
(a) Warm up engine.
(b) When using hand±held tester:
(1) Connect the hand±held tester to the DLC3.
Idle speed: 650 to 750 rpm
NOTICE:

Check the idle speed with the cooling fan OFF.

Switch off all accessories and air conditioning before
connecting the test prove to the terminal.
HINT:
Please refer to the hand±held tester operator's manual if you
need help to select DATA LIST.
(c) When not using hand±held tester.
(1) Using SST, connect the tachometer test prove to
terminal 9 (TAC) of DLC3.
SST 09843±18040
(2) Check the idle speed.
Idle speed: 650 to 750 rpm
9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Disconnect the injector connectors.
(c) Remove the ignition coil.
(d) Remove the spark plugs.
(e) Inspect cylinder compression pressure.
SST 09992±00500
(1) Insert a compression gauge into the spark plug
hole.
(2) Fully open the throttle.

(3)While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1,300 kPa (13.3 kgf/cm
2, 189 psi)
Minimum pressure:
1000 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 is low, pour a small amount of engine oil into the cylinder through the
spark plug hole and 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, 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
(e)If the CO/HC concentration does not conform to specifications, perform troubleshooting in the order given below.
(1)Check heated oxygen sensor operation. (See page 12±6)
(2) See the table below for possible causes, and then inspect and repair the applicable causes ifnecessary.

(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the paths with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.
(d) Remove the fringe bolt of camshaft timing gear.
NOTICE:

Be sure not to remove the other 4 bolts.

If reusing the camshaft timing gear, release the
straight pin lock first, and then install the gear.

14. INSTALL CAMSHAFT TIMING GEAR ASSY
(UNLEADED GASOLINE)
(a) Put the camshaft timing gear and the camshaft together
with the straight pin off the key groove.
(b) Turn the camshaft timing gear assembly to the left direc-
tion (as shown in the illustration) while lightly pushing it to-
ward the camshaft. Push further at the position where the
pin gets into the groove.
NOTICE:
Be sure not to turn the camshaft timing gear to the retard
angle side (to the right direction).
(c) Check that there is no clearance between the gear's
fringe and the camshaft.
(d) Tighten the fringe bolt with the camshaft timing gear fixed.
Torque: 54 N

(e) Check that the camshaft timing gear can move to the re-
tard angle side (to the right direction), and is locked at the
most retarded position.
