filter element, clean it with compressed air.

• If any dirt or a blockage remains even after

cleaning the air cleaner filter element with

compressed air, replace it.

6. INSPECT VALVE LASH ADJUSTER NOISE

(a) Rev up the engine several times. Check that the

engine does not emit unusual noises.

If unusual noises occur, warm up the engine and

idle it for over 30 minutes. Then repeat this

procedure.

HINT:

If any defects or problems are found during the

inspection above, perform lash adjuster inspection

(See page EM-87).

7. INSPECT IGNITION TIMING

(a) Warm up the engine.

(b) When using the intelligent tester:

Check the ignition timing.

(1) Connect the intelligent tester to the DLC3.

(2) Enter DATA LIST mode with the intelligent

tester.

Ignition timing:

8 to 12°BTDC at idle

HINT:

Refer to the intelligent tester operator's manual

for help when selecting the DATA LIST.

Check the ignition timing.

(1) Using SST, connect terminals 13 (TC) and 4

(CG) of the DLC3.

SST 09843-18040

NOTICE:

• Confirm the terminal numbers before

connecting them. Connection with a

wrong terminal can damage the engine.

• Turn off all electrical systems before

connecting the terminals.

• Perform this inspection after the cooling

fan motor is turned off.

(2) Remove the V-bank cover.

(3) Pull out the red lead wire harness.

(4) Connect the tester terminal of the timing light to

the red lead wire as shown in the illustration.

NOTICE:

Use a timing light which can detect the first

signal.

(5) Check the ignition timing at idle.

Ignition timing:

8 to 12°BTDC at idle

NOTICE:

When checking the ignition timing, the

transmission should be in neutral.

HINT:

Run the engine at 1,000 to 1,300 rpm for 5

seconds, and then check that the engine rpm

returns to idle speed.

(6) Disconnect terminals 13 (TC) and 4 (CG) of the

DLC3.

(7) Check the ignition timing at idle.

Ignition timing:

12 to 22°BTDC at idle

(8) Confirm that the ignition timing moves to the

advanced angle side when the engine rpm is

increased.

(9) Remove the timing light.

8. INSPECT ENGINE IDLE SPEED

(a) Warm up the engine.

(b) When using the intelligent tester:

Check the idle speed.

(1) Connect the intelligent tester to the DLC3.

(2) Enter DATA LIST mode with the intelligent

tester.

Idle speed:

600 to 700 rpm

NOTICE:

• When checking the idle speed, the

transmission should be in neutral.

• Check the idle speed with the cooling fan

off.

• Switch off all accessories and air

conditioning before connecting the

intelligent tester.

HINT:

Refer to the intelligent tester operator's manual

for further details.

Check the idle speed.

(1) Using SST, connect the tachometer test probe

to terminal 9 (TAC) of the DLC3.

SST 09843-18030

(2) Check the idle speed.

Idle speed:

600 to 700 rpm

9. INSPECT COMPRESSION

(a) Warm up and stop the engine.

(b) Disconnect the injector connectors.

13).

(d) Remove the 6 ignition coils.

(e) Remove the 6 spark plugs.

(f) Check the cylinder compression pressure.

(1) Insert a compression gauge into the spark plug

hole.

(2) While cranking the engine, measure the

compression pressure.

Compression pressure:

1.4 MPa (14 kgf/cm2, 199 psi)

Minimum pressure:

0.98 MPa (10 kgf/cm2, 142 psi)

Difference between each cylinder:

0.1 MPa (1.0 kgf/cm2, 15 psi)

NOTICE:

• Always use a fully charged battery to

obtain an engine speed of 250 rpm or

more.

• Check the other cylinders' compression

pressure in the same way.

• This measurement must be done as

quickly as possible.

(3) 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 stuck

or seated improperly, or there may be

leakage in the gasket.

(g) Install the 6 spark plugs.

Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf)

(i) Install the intake air surge tank. (See page FU-17).

10. INSPECT CO/HC

(a) Start the engine.

(b) Run the engine at 2,500 rpm for approximately 180

seconds.

(1.3 ft) into the tailpipe during idling.

(d) Check CO/HC concentration at idle and/or 2,500

rpm.

HINT:

Check regulations and restrictions in your area

when performing 2 mode CO/HC concentration

testing (engine check at both idle speed and at

2,500 rpm).

If the CO/HC concentration does not comply with

regulations, perform troubleshooting in the order

given below.

(1) Check A/F sensor and heated oxygen sensor

operation.

(2) See the table below for possible causes, and

then inspect and repair.

CO HC Problems Causes

Normal High Rough idle

1. Faulty ignitions:

– Incorrect timing

– Fouled, shorted or improperly gapped plugs

2. Incorrect valve clearance

3. Leaks in intake and exhaust valves

4. Leaks in cylinders

(2) While releasing the belt tension by turning the

belt tensioner counterclockwise, put the V-

ribbed belt on the tensioner pulley.

NOTICE:

• Put the backside of the V-ribbed belt on

the tensioner pulley and idler pulley.

• Check that the V-ribbed belt is properly

set to each pulley.
