tion.
(c) Check that the back-up light is lit and the reverse warning buzzer sounds only when the shift lever is
set in R position.
If a failure is found, check the continuity of the park/neutral position switch.
2. ADJUST PARK/NEUTRAL POSITION SWITCH ASSY

BRAKE BOOSTER ASSY (From July, 2003)
ON-VEHICLE INSPECTION
1. INSPECT BRAKE BOOSTER
(a) Air tightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-
press the brake pedal several times slowly.
HINT:
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is air tight.
(2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is air tight.
(b) Operating check.
(1) Depress the brake pedal several times with the igni-
tion switch OFF and check that there is no change
in the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Check vacuum check valve.
(1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
engine, and no ventilation from the engine to the
booster.
(4) If any fault is found, replace the vacuum check
valve.

that the engine speed returns to the idle speed.
(6) Disconnect terminals 13 (TC) and 4 (CG) of the
DLC3.
(7) Inspect the ignition timing at idle.
Ignition timing: 7 to 24 BTDC
(8) Confirm that the ignition timing advances when the
engine speed is increased.
(9) Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
(a) Warm up the engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or OBD II scan tool.
Idle speed: 630 to 730 rpm
NOTICE:

When checking the idle speed, the transmission is in the neutral position.

33. INSTALL CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being installed. If the
camshaft is not kept level, the cylinder head or camshaft
may be damaged. To avoid this, the following steps must
be carried out.

and driven gears.
(c) Place the camshaft on the cylinder head.
(d) Install the 5 bearing caps in their proper locations.
(e) Apply a light coat of engine oil to the threads of the bear-
ing cap bolts.
(f) Using several steps, tighten the 10 bearing cap bolts uni-
formly in the sequence shown in the illustration.
Torque: 16 NVm (163 kgfVcm, 12 ftVlbf)
(g) Remove the service bolt.
34. INSTALL TIMING BELT NO.3 COVER

timing belt cover.
HINT:
If there is a trace of water intrusion when checking visually, re-
pair the gasket with seal packing when the crack length is within
2 to 3 cm (0.79 to 1.18 in.). Replace the gasket when the crack
length is 3 to 4 cm (1.18 to 1.57 in.) or longer.
