(c) Please refer to the TOYOTA hand−held tester or OBD II scan tool operator’s manual for further details.
3. CONNECT TIMING LIGHT TO ENGINE
4. CHECK IDLE SPEED
(a) Race the engine speed at 2,500 rpm for approx. 90 se- conds.
(b) Check the idle speed. Idle speed: 650 ± 50 rpm
5. INSPECT AND ADJUST IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the DLC1. SST 09843−18020
(b) Using a timing light, check the ignition timing. Ignition timing: 3 ° BTDC @ idle
(Transmission in neutral position and A/C OFF)
(c) Loosen the hold−down bolt, and adjust by turning the dis-
tributor.
(d) Tighten the hold− down bolt, and recheck the ignition tim-
ing.
Torque: 18 N·m (180 kgf·cm, 13 ft·lbf)
(e) Remove the SST from the DLC1. SST 09843−18020
6. FURTHER CHECK IGNITION TIMING Ignition timing: 2 − 13° BTDC @ idle
(Transmission in neutral position and A/C OFF)
HINT:
The timing mark moves in a range between 2 ° and 13° .
7. DISCONNECT TIMING LIGHT FROM ENGINE
8. DISCONNECT TOYOTA HAND −HELD TESTER OR
OBD II SCAN TOOL

INSPECTION
1. INSPECT TIMING CHAIN AND TIMING GEARS
(a) Measure the length of 16 links with the chain fully
stretched.
Maximum chain elongation: 146.6 mm (5.772 in.)
If the elongation is greater than maximum, replace the chain.
HINT:
Make the same measurements pulling at 3 or more places se-
lected at random.
(b) Wrap the chain around the timing gear.
(c) Using vernier calipers, measure the timing gear diameter with the chain.
NOTICE:
Vernier calipers must contact the chain rollers for measur-
ing.
Minimum gear diameter (w/Chain):
Camshaft126.0 mm (4.961 in.)
Crankshaft65.4 mm (2.575 in.)
If the diameter is less than minimum, replace the chain and
gears.
2. INSPECT CHAIN TENSIONER SLIPPER AND VIBRA-TION DAMPER
Measure the chain tensioner slipper and vibration damper
wears. Maximum wear: 1.0 mm (0.039 in.)
If the wear is greater than maximum, replace the slipper and/or
damper.
3. INSPECT OIL JET
Check the oil jet for damage or clogging.
If necessary, replace the oil jet.
