2c) When fault diagnosis tester is not used
(1) Shorting fault diagnosis interface socket 13 (TC) terminal and 4(CG) terminal.
Notice:
zEnsure correct connection, otherwise the engine will be damaged.
zSwitch off all electrical appliance system.
zCheck when disconnecting cooling fan motor.
(2) Using timing light to check ignition timing.
Ignition timing: 10 ± 2° BTDC at idle
Notice:
(1) Transmission shift lever should be in neutral position when checking ignition timing.
(2) Running engine at 1,000-1,300rpm for 5s and check at idle.
(3) Remove the tester on fault diagnosis socket.
(4) Ignition timing advance angle becomes larger when the engine roate speed is higher.
(5) Remove timing light.
8. Check engine idle See (Figure 3)
Notice:
zCheck idle when cooling fan motor is disconnected.
zSwitch off all electrical accessories and A/C.
9. Check compression pressure See (Figure 4)
(a) Engine switched off.
(b) Detach high voltage cable.
(c) Detach spark plug.
(d) Check the compression pressure in the cylinder.
(1) Insert pressure gauge into the hole of the spark plug.
(2) Throttle valve full open.
(3) Crank the engine, measure the compression pressure. MR479Q 800±50 (rpm)
MR479Q A 800±50 (rpm)
MR481Q A 800±50 (rpm)Table 2(a) Warm up the engine.

3The Min. compression pressure: 980 kPa
The tolerance range of the cylinders pressure: 100 kPa
Notice:
zEnsure sufficient battery power and the engine speed is no less than 250 RPM (revolutions per minute).zCheck the compression pressure of other cylinders in the same way.
zComplete the measure as quick as possible.
(4) If the compression pressure in several cylinder is too low, fill some engine oil to the cylinder via the
hole of the spark plug. Check by repeating step 1-3.
Hint:
zIf the compression pressure is improved after filling oil, the piston ring or the cylinder may be abrased
or damaged.
zIf the pressure is still too low, the valve is stagnation or poor seal, or there is a leakage in gasket.
10. Check CO/HC
(a) Start engine.
(b) Running engine at 2500rpm for approximately 3 minutes.
(c) Insert CO/HC meter testing probe into tailpipe at least 40cm during idling.
(d) Check CO/HC concentration at idle and 2500rpm.
Hint:
zComplete measurement within 3 minutes.
zTest the CO/HC emission concentration at idle and 2500 rpm on QC/T630-1999 standard.
(e) Take the following steps to diagnose the fault if the CO/HC concentration does not comply with standard .
(1) Check the oxygen sensor operation.
(2) See (Table 3) for the possible cause and check and repair.

76. Adjust intake valve clearance
(a) Detach intake camshaft
Notice:
Because the camshaft end play is quite small, keep camshaft horizontal when removing it. If not, cylinder
head may be partially damaged by the thrust force£¬it may stuck or damage camshaft when turning crankshaft.
Take the following steps to avoid the damage:
(1) Turn the pulley to access the hole on the camshaft drive gear where the counter gear is installed. See
(Figure 12).
Hint:
The above condition allows the cylinders No. 1 and No. 3 of the intake camshaft to push up the valve tappet.
(2) Remove bolt and bearing cap No. 1.
(3) Install camshaft counter gear to drive gear with service bolt. See (Figure 13).
(4) Uniformly loose and remove 8 bearing cap bolts in several passes as
shown in the figure. See (Figure 14).
(5) Remove 4 bearing caps and camshafts.Figure 11
Figure 14 Figure 12 Figure 13

8Notice:Due to the small end play on camshaft, the cylinder head may be damaged by the thrust force when removingit, it may stuck or damage camshaft. Take the following steps to avoid damage: (1) Turn the crankshaft pulley to make exhaust camshaft dowel pin is a bit higher than the cylinder head. See(Figure 15). (2) Align the matchmark on each gear to engage intake camshaft gear and exhaust camshaft gear. See(Figure 16).
(3) When the gears are engaged, install the intake camshaft bearing onto bearing journal.
Hint:
The intake camshaft lobe of cylinder 1 and 3 can jack up their own valve tappet.
(5) Install 4 bearing caps to the right position.
(6) Apply a light layer of engine oil on the thread and under the head of bearing cap bolts.
(7) Uniformly install and tighten 8 bearing cap bolts in several times, in the sequence shown in the figure.
Torque: 13N. m
(8) Remove service screw.
(9) Install the bearing cap No. 1. in the direction of the forward arrow mark.
(10)Apply a light layer of engine oil on the thread and under the head of bearing cap bolts.
